Glossary of Terms
The Home Dadeland Pools glossary is a complete list of common swimming pool definitions. These definitions will benefit pool owners when talking to your local pool store or service guy. If you have any additional questions on terminology or would like to add to the glossary please email Home Dadeland Pools your requests.
ACID: Liquid (muriatic acid) or dry granular (sodium bisulfate) substance used to lower the pool's pH (toward a more acidic condition) or to lower total alkalinity levels.
ACID DEMAND: A titration test used to determine proper amounts of acid (or pH decreaser) to reach correct levels. For example, to lower pH from 8.0 to 7.6, your pool may "demand" 2qts. Of acid.
AIR BLEEDER ASSEMBLY: Located on the top of the filter and sometimes accompanied by a pressure gauge, the bleeder is opened to release air trapped in the filter.
AIR BUBBLES WITH SOLAR HEATERS: Your pump is probably undersized for a solar system. Solar systems require at least one pump size larger to push water to your roof. The increase in pressure causes an equal increase in vacuum.
ALGAE
Green Algae- Causes pool water to become cloudy and take on a greenish tint. It can be free floating or attached to the pool surfaces. Green algae will usually come off with a wire brush and removed from the water with high chlorination.
Mustard Algae (Yellow)- Usually lives in areas of low sunlight . This algae is a powdery texture on the pool surface and walls. Established algae are chlorine resistant and must be removed with strong chlorine, constant brushing and filter cleaning.
Black Algae (Blue-Green) - Looks like small circular spots that are firmly attached to the surface. Black algae builds itself on top of each other creating very strong algae with roots. Granular chlorine and a frequent wire brushing is recommended. Also a replace cartridge filters; replace sand in sand filters and backwash DE filters.
ALGAECIDE : Meaning, to kill algae. Algaecides perform best as a backup to a routine sanitation program. They also help to kill airborne spores as they blow into the pool. A variety of algae treatment products are available including copper and silver compounds, poly-quat compounds, chlorine enhancers , and herbicides.
ALGAESTAT : An algaecide kills algae, while an algae stat retards and prevents its genesis and growth.
ALKALINE : are best known for being bases (compounds with pH greater than 7) that dissolve in water. Alkaline is commonly used as a synonym for base, especially for soluble bases.
ALKALINITY : Alkaline refers to the condition where the water's pH is above 7.0 (neutral) on the pH scale. It is the opposite of acidic. Alkalinity is the amount of carbonates and bicarbonates in the water, measured in "parts per million" (ppm) of Total Alkalinity.
ALUMINUM : A silvery white and ductile member of the poor metal group of chemical elements
ALUMINUM SULFATE : Also known as "alum;" this product is used as a flocculent which attracts suspended particles in the water together (green or cloudy pools). "Alum" sinks everything to the bottom which is then vacuumed to waste. A small amount of "alum" can also be used as a sand filter additive.
ANION : A negatively charged ion, which has more electrons in its electron shells than it has protons in its nuclei, is known as an anion due to its attraction to anodes.
AUTOMATIC POOL CLEANER: A device which agitates or vacuums debris from the walls and floor of the pool.
BACKWASH: The process of thoroughly cleaning the filter medium and/or elements by reversing the flow of water and disposing of the contaminated water through waste.
BACTERIA: From a health perspective, the most dangerous micro-organisms which may be living in the pool water. Some are pathogens, which can cause infectious diseases.
BACTERICIDE : Kills bacteria. Chlorine is a bactericide and germicide. Silver algaecides are actually more bactericide, and are useful on pink "algae."
BALANCED WATER: Balanced water is the result when all of your chemical parameters are where they should be and thus balance each other. The key components of water balance are pH, Total Alkalinity, Calcium Hardness, and Temperature; as measured using the Langelier Index of water balance.
BALL VALVE: A device with a hollowed out ball inside which can be turned with an external handle to decrease or increase flow.
BASE: Those chemicals of alkaline nature which will counteract the pH of an acid eventually neutralizing at 7.0. Common bases used around the pool would include Soda Ash, Sodium Bicarbonate, and Sodium Carbonate
BASE DEMAND: A titration test used to determine proper amounts of base (pH increaser) to reach correct levels. For example, to raise pH from 7.2 - 7.6, your water may need 2 cups of soda ash.
BLOWER: Plumbed into the spa return line, air is injected to produce fun bubbles and a hydrotherapy effect in the spa.

BOOSTER PUMP: Secondary to the filter pump, a booster pump is used to power an automatic pool cleaner such as Polaris or Letro.
BREAKPOINT CHLORINATION: Also referred to as super chlorination or Shock treatment.
This is the process by which combined chlorine is destroyed and converted into nitrogen, water, and chlorine salt. The levels of the total chlorine will reach a point where they will drop suddenly after rising steadily in response to a shock treatment. This is necessary to reach this point in order to rid the pool of chloramines. Shock treatments can be performed with products that do not contain chlorine such as potassium monopersulfate, potassium dipersulfate and hydrogen peroxide. These are all oxidizers not disinfectants.
If you accidently over-treat, Free Chlorine residuals may be too high and can be reduce instantly with Sodium Thiosulfate
BROMINE: A member of the halogen family commonly used as a sanitizer in spas, because of its resistance to hot water with rapid pH fluctuations. Swimming pool service Miami Florida
BTU: British Thermal Unit. A unit of measurement for the use of gas by a gas appliance. Pool heaters are rated by their consumption.
BUFFER: A base such as Sodium Bicarbonate (Baking Soda), added to your pool will increase alkalinity which increases the buffering capacity of the pool; your pool's resistance to pH change.
BUFFERING CAPACITY: The ability of the pool to resist changes in pH, which prevents water balance. The buffering capacity is given by the alkalinity, a close cousin to pH. If your pH bounces, or resumes previous levels soon after adjustment your buffering capacity is too low. Check your total alkalinity.
CALCUIM : Calcium is a soft grey alkaline earth metal.
CALCIUM CARBONATE : Known as scale, crystalline deposits of calcium may form on your pool surfaces, equipment, or even line your pipes like cholesterol in your arteries. Properly balanced water can prevent this.
CALCIUM CHLORIDE : The flaked calcium salt used to raise levels of Calcium Hardness in your pool water. Also good for snow melting.
CALCIUM HARDNESS : A titration test is used to determine levels of the mineral calcium dissolved in the pool water.
CAPACITY: The total number of gallons of pool water your pool contains (gallon age).
CAPACITOR: The Capacitor is the battery for your pool motor. It provides the energy needed while starting, to reach 3450 rpm quickly. Replace your capacitor when the shaft can be spun freely with a wrench or by hand, and when powering the motor, you hear a 'buzz' or a 'hum' from the motor, but no impeller movement. Replace your old capacitor with an exact match to the 'MFD' number on the new capacitor.
CARBON DIOXIDE: A gas, which when present in the water, provides necessary food for the growth of algae.
CARBONATE : Primary in the makeup of total alkalinity and TDS.
CARTRIDGE: One type of filtration, the cartridge is a pleated, porous element through which water is passed through...
CHECK VALVE: A one way flow device.
CHITIN: A naturally occurring polymer found in the shells of crabs and lobsters. Contained in the product " Sea-Klear ." Chitin acts as a coagulant and flocculent for oils, metals, and organic materials.
CHELATOR: A chelating agent is a water soluble molecule that can bond tightly with metal ions, keeping them from coming out of suspension and depositing their stains and scale onto pool surfaces and equipment. Similar to sequestering agents, chelators are found in such products as "Resist" and "Sea-Klear." |
|
CHLORAMINES : The chlorine molecule is strongly attracted to nitrogen and ammonia. When these two combine they form a chloramine, which are undesirable, foul smelling, space taking, compounds that require shocking the pool water to get rid of.
CHLORINE: A member of the halogen family of sanitizers, its use in swimming pools is in the elemental form of a gas, liquid, granular, or tablet compound. When added to water it acts as an oxidizer, sanitizer, disinfectant, and all around biocidal agent.
CHLORINE FREE AVAILABLE: Free Available Chlorine is that which is active, not combined with ammonia or a nitrogen molecule, and ready to react to destroy organic material.
CHLORINE COMBINED: That portion of total available chlorine left over when free available is subtracted. The measure of chlorine which has already attached itself to other molecules or organisms. Most of this is made up of chloramines.
CHLORINE GENERATOR: A miniature chlorine factory. This device creates its own sanitizer for your pool. Home Dadeland Pool service in Miami offers the best price in Miami on Chlorine generators and installations.

COPPER: An effective algae stat and algaecide. Copper as elemental is used in many pools in products like " Pool trine."
COPPER SULFATE: Similar to aluminum sulfate, this chemical provides a coagulating and flocculent function in water. Used mainly in ponds, a large amount of copper sulfate would stain a swimming pool.
CONDITIONER: Also called Cyan uric Acid (CYA) or a stabilizer, this chemical provides a shield from the sun around the chlorine molecule, extending the efficacy; saving you money.
CYANURIC ACID : A granular chemical added to the pool water which provides a shield to chlorine for protection from UV radiation, which disrupts the molecule, destroying its sanitizing ability.
DIATOMACEOUS EARTH: The filtering medium of the DE filter, this dry powder is the fossilized remains of the ancient plankton; diatom.
DIATOMACEOUS EARTH FILTER: A filter tank containing fabric covered grids which hold the DE powder up against the flow of the water.

DIVERTER VALVE: Used in a twin port skimmer, a diverter allows the operator to manipulate the amount of flow from the main drain and skimmer to the pump.
DRY ACID: Sodium bisulfate, a granular form of acid used to lower pH and alkalinity in the water. It is safer and less caustic than muriatic acid. Usually available as a "pH decreaser."
EFFLUENT: The water that flows out of the pump on its way through the filter, heating, treating equipment, and then returning to the pool. Also known as the pressure side.
ENZYMES: Used in swimming pool formulations designed to break down and digest oils in a pool or spa similar to the way enzymes are used in oil spill clean-up efforts.

FILM-X: A compound of citric acid used in cleaning plaster and other pool areas. Safe replacement for muriatic acid.
FOAMING: A term used to describe surface foam on your water, esp. in spas/hot tubs. Foaming is caused by high TDS levels working in combination with soft water and oils. Certain low grade algaecides can foam when added to pool or spa. Use enzymes for foam control.
FLOCCULENT: Essentially the same as a coagulant, this chemical (such as alum) is used to combined suspended alkaline material and/or algae into a heavy gel, which sinks to the bottom for vacuuming to waste.
FLOW RATE : The quantity of water flowing past a specific point in a specified time (e.g. the number of liters flowing through the filter in 1 hour).
GROUND-FAULT CIRCUIT-INTERRUPTER: A GFCI device protects a circuit from branching off by de-energizing the path of electricity very quickly when it senses current loss. An important safety device around water (the pool?).
GROUT: a construction material used to embed rebar in masonry walls, connect sections of pre-cast concrete, fill voids, and seal joints (like those between tiles). Grout is generally composed of a mixture of water, cement, sand and sometimes color tint which is applied as a thick liquid and hardens over time, much like mortar.
GUNITE : A dry mixture of cement and sand mixed with water at the "gun"; hence the name. A gunite operator "shoots" the pool's rough shape, while finishers trowel after.
HARD WATER - Hard water is the most common problem found in the average home. Hard water is water that contains dissolved hardness minerals above 1 GPG and contains Calcium, manganese and magnesium. Hard water can quickly destroy you pools surface and equipment with scale. This scale can plug your pipes and hot water heater, causing premature failure, necessitating costly replacement. If your water tests over 3 GPG hard, you should mechanically soften it.
HEAT EXCHANGER: A set of 8 or 10 ribbed copper tubes that absorb the heat produced below it and transfer it to the water cycling through its tubes.
HEAT PUMP: The antithesis of the air conditioner, the heat pump's cooling coil removes heat from the air while the condenser coil transfers it to water cycling through it.

HYPOCHLORITE: A family of chlorine compounds such as Calcium Hypochlorite and Lithium Hypochlorite, both granular, and the liquid Sodium Hypochlorite. When these compounds contact water, they release Hypochlorous Acid, the active sanitizing agent.
HYDROSTATIC PRESSURE: A force involving built up ground water which creates upward pressure beneath the pool shell.
HYDROSTATIC RELIEF VALVE: Fitting(s) installed in the floor of the pool designed to manually or automatically release hydrostatic pressure beneath the pool by allowing ground water into the pool.
IMPELLER: The rotating vanes of a centrifugal pump; its action creates the flow of water.
INFLUENT: The water coming into and up to the impeller from the suction lines. These pipes are under vacuum pressure.
IONIZER: An ionizer is a device mounted on your return line, and through which water flowing will receive charged metal ions. Manufacturers may use a copper anode and/or silver. Copper is an algaecide and algae stat, while silver is known for its properties as a bactericide. This electric, limited technology has been replaced by the Vision System.
IRON : Usually introduced into the water from iron plumbing or from well water, Ferric Iron can stain surfaces, while Ferrous Iron will turn your water a clear green color.

J ANDY VALVE: A brand name of a three way valve, which has simplified pool plumbing.
LANGELIER INDEX: Also called the Saturation Index, Mr. Langelier devised a system to determine water balance by assigning values to levels of pH, Total Alkalinity, Calcium Hardness and water Temperature. When all parameters are in balance, the water will neither be corrosive or scaling. The formula is "SI = pH + TF + CF + AF - 12.1."
LATERALS: Elongated, capped plastic nipples at the bottom of a sand filter which are slotted to allow for water passage while keeping the sand in the filter tank.
LOW WATER SUCTION: An influent fitting, typically low on the wall in the deep end of a vinyl liner pool. A cheaper alternative to a main drain.
MAGNESIUM: A light, ductile, silver-white, metallic element. Its presence in high non-chelated concentrations can lead to stains & scale when conditions are right
MINERALS: Such as Calcium, Manganese, Magnesium, Nickel, Copper, Silver, Iron, Cobalt or Aluminum. Their presence in high non-chelated concentrations can lead to stains & scale when conditions are right.
MECHANICAL SEAL: A seal behind the impeller which prevents water from running out along the shaft of a motor. Aka; pump seal.
MOTOR: A machine for converting electrical energy into mechanical energy. Your motor is known as the dry end of the filter pump. It drives the impeller, which moves the water.
MULTIPORT VALVE: A 4 or 6 position valve combining the functionality of several valves into one unit, revolutionizing pool plumbing. The six common functions are described below:
- FILTER: Keep it here 99%, except when backwashing, rinsing or wasting
- RINSE: Use this setting for 20 seconds after backwashing to rinse tank
- RECIRCULATE: Use this if the filter's broken; at least you're circulating.
- BACKWASH: Use this setting to reverse the flow in the filter and send water out of the waste line. Make sure valves are open or hoses rolled out
- CLOSED: Put here to close off flow from the pool, usually to work on the equipment. Do not operate pump with valve in closed position
- WASTE/DRAIN: Another filter bypass setting, but this setting sends the water out of the waste pipe (hose), instead of returning it to the pool. This setting is used to lower pool water level or to vacuum to waste.
MURIATIC ACID: The liquid dilution of Hydrochloric Acid used to lower pH and alkalinity, and to remove mineral stains and scale. Extremely caustic and corrosive.
NASCENT OXYGEN: A single oxygen atom, not yet bonded to anything. Extremely powerful oxidizer when harnessed.
NITROGEN: When combined with chlorine, nitrogen creates chloramines, which do not belong in our pool. Nitrogen can be found in many swimmer wastes (perspiration, suntan oil, hair tonics, etc.) or is introduced by other means.
NON-CHLORINE SHOCK: A granular form of potassium permonosulfate, used to oxidize materials such as microorganisms, contaminants or chloramines.
|
O-RING: A loop of elastomer with a round (o-shaped) cross-section used as a mechanical seal or gasket. They are designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
OTO: Another method of testing for free available chlorine levels in your pool, as in an OTO test kit.
OXIDATION: The "burning up" of organic waste and compounds in the pool water. It also refers to what you may see on your metal pool surfaces if your water is corrosive. Rust is a form of this kind of oxidation.
OZONE: The molecule containing three atoms of oxygen; known to be a very powerful sanitizer. zone producing equipment creates this molecule by UV radiation or corona discharge generators.
pH: The scale of relative acidity or alkalinity, expressed in logarithmic numbers from 0 - 14, with 7.0 being neutral. What's really being measured is the hydrogen ion concentration.
PLASTER: A common type of interior finish applied over the concrete shell of an in-ground swimming pool. Home Dadeland offers renovations of your Miami pool surface with over 50 years of experience and stands behind every pool that IS COMPLETED WITH A FULL WARRENTY.
POLYMER: An algaecide / algae stat made up of repeating polymer molecules. Used for green algae and available in varying strengths.
PPM: Parts per million. A method of assigning value to certain concentrations of chemicals in the water. For example, alkalinity should be kept at 80-120 parts per million, by weight and in relation to the water it's dissolved in.
PRESSURE CHECK: A test for the rate of water flow; also a test for leaks in plumbing by placing a line in question under pressure and waiting for the pressure to drop.
PRESSURE GAUGE: A device indicating pressure in a filter system. Provides a determination of how the system is operating, and informs us when service is required.
PRESSURE SIDE: The return side of the plumbing. The section from the pump impeller towards the pool.
PRESSURE SWITCH: A switch used in pool heaters which opens when the flow rate is insufficient or safe heater operation. This disrupts the circuit in the heater, preventing it from firing.
PUMP: A mechanical wet-end, powered by an electric motor, which causes hydraulic flow and pressure for the circulation of the pool water.
RATE OF FLOW: Quantity of water flowing past a designated point within a specified time period, measured in gallons per minute (gpm).
REAGENT : The chemical indicators used in testing water balance. (All the little bottles or tablets in your test kit).
RESIDUAL: Usually refers to free available chlorine levels remaining in the pool after initial treatment or activity with contaminants.
RESTRICTED FLOW: The term used to describe a condition preventing full flow of water. Restriction can occur with full skimmer or strainer baskets, obstructions in the plumbing, dirty filter, undersized plumbing or equipment, or placing devices like, heaters, cleaners or fountains in the circulation system. Restriction on the suction side creates higher vacuum, (or suction) while on the pressure side creates higher pressure.
SAND FILTER: A filter tank, usually fiberglass or ABS plastic, filled with sand and gravel. The pump diffuses water over the top of the sand bed, and forces it through the sand and into the laterals on the bottom. Home Dadeland Pools voted best pool cleaner in Miami south Florida
SANITIZER: A chemical agent used to remove unwanted contaminants.
SCALE : Usually whitish in color, scale forms on pool surfaces and equipment when mineral salts are forced out of solution. A scaling condition is one in which calcium hardness; pH and/or alkalinity levels are out of balance.
SEQUESTERING AGENT: A sequestering agent ties-up minerals tightly in solution, preventing their precipitation, which colors the water and/or stains the pool. Synonymous to chelators, these are commonly called stain & scale chemicals.
SKIMMER: A surface skimmer is a plumbing fitting set at water level, containing a weir mechanism and a debris basket. The skimmer is part of the suction side circulation system.
SKIMMER BASKET: Beneath the lid, the basket strains debris, as the first line of defense in filtering the water.
SHOCK: As a noun it loosely describes the products used in shocking, such as hypochlorites, potassium permonysulfate or hydrogen peroxide. As a verb it describes the act of bringing the sanitizer level up so high that breakpoint chlorination is reached. When breakpoint is reached, a "shock" or perhaps a "lightning bolt" is a better analogy, is sent through the water, tearing apart molecules and slashing through cell walls. Ultimate purification, man.
SHOTCRETE: A different type of application of the concrete and sand mix which is used to "shoot the shell". Gunite is pumped dry and mixed with water at the gun, whereas shotcrete is pumped wet.
SODA ASH: A base, used to counteract an acidic condition by raising pH.
SODIUM BICARBONATE (baking soda): Another base, however its properties will increase alkalinity more than pH. Used to raise Total Alkalinity levels.
SODIUM BISULFATE: A granular form of acid, used to counteract a scaling condition by lowering pH and/or alkalinity.
SODIUM HYPOCHLORITE: Liquid chlorine used in pools, identical yet stronger than Clorox bleach.
SODIUM TETRABORATE: New technology that renders algae incapable of processing carbon dioxide, which they need to live.
SODIUM DICHLOR: A granular form of chlorine that is stabilized with cyan uric acid. Used for shocking and super-chlorination.
SOFT WATER: Water that has low calcium and/or magnesium content. Soap lathers easily in soft water. Swimming pool Pool services offered in Miami including full chemical balance, vacuuming
STABILIZER : See Cyanuric Acid. Stabilizers, also called conditioners, can be added directly to your pool to extend your chlorine efficacy. Cyan uric acid is already added to certain "stabilized" products such as Trichlor tablets and Sodium Dichlor.
STANDPIPE: Vertical pipe that carries water from the hub and lateral assembly to or from the multiport valve on a top mount sand filter.
STR AINER BASKET: The second line of defense is a basket at the pump. The holes in this are smaller than those in a skimmer basket, and prevent the pump impeller from clogging up.
SUCTION SIDE: The plumbing prior to and carrying water to the pump. This side is under vacuum pressure.
SUPER-CHLORINATION: Applying 7 - 10 times the normal amounts of chlorine to the pool as an added "boost" for contaminant removal. Some refer to super-chlorinating as being less than shocking, in that breakpoint thresholds are not reached, or the terms may be used synonymously.
TDS: See Total Dissolved Solids.
TEST KIT: A method used to test the water balance and sanitizing level of your pool water.
TIME CLOCK: A mechanical device that controls the timed operation of your electrical equipment, primarily your filter and booster pumps.
TITRATION: A method of testing for total alkalinity, calcium hardness and acid/base demand by adding a titrant, drop by drop until a color change is observed.
TOTAL ALKALINITY: The ability of the pool water to resist changes in pH. The "buffering" capacity of the water. Additions of Sodium Bicarbonate will increase the levels, expressed in ppm.
TOTAL DISSOLVED SOLIDS (TDS): A measure of everything that has ever dissolved in the water; all the matter that is in solution. High TDS levels can oversaturate your water, causing all sorts of reactions.
TRICHLORO-S-TRIAZINETRIONE: a chemical compound used as an industrial disinfectant, bleaching agent and a reagent in organic synthesis. This white crystalline powder, which has a strong "chlorine odour," is sometimes sold in tablet or granule form for domestic and industrial use.
TURNOVER: The amount of time it takes your pump to move all the water in your pool through the filter and back again. Usually, pools are designed for an eight hour turnover.
VACUUM: Refers to the low pressure condition created in the suction line. Also refers to the cleaning process of sucking leaves, algae and debris from the pool floor. Miami pool service
VALVES: A device placed in the plumbing line which restricts or obstructs water flow to create desired hydraulics, or may permit flow in one direction only (as in a check valve).
VENTURI: Increasing water velocity by restricting pipe size usually accomplished by a spa jet.
VOLUTE : A volute is a curved funnel increasing in area to the discharge port. It is often used with impeller pumps. As the area of the cross-section increases, the volute reduces the speed of the liquid and increases the pressure of the liquid. One of the main purposes of a volute casing is to help balance the hydraulic pressure on the shaft of the pump. However, this occurs best at the manufacturer's recommended capacity. Running volute-style pumps at a lower capacity than the manufacturer recommends can put lateral stress on the shaft of the pump, increasing wear-and-tear on the seals and bearings, and on the shaft itself.
