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, it's 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 an 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 TOTAL AVAILABLE:  The sum of combined and free chlorine levels.  With a DPD test kit,  one determines free available level, then total available.  The difference, if any, is the level of combined chlorine.

CHLORINE GENERATOR:  A miniature chlorine factory.  This device creates its own sanitizer for your pool.

CHLORINATOR:  Devices which allow for the safe controlled introduction of chlorine into the water.  

CHLORINE DEMAND:  The quantity of free available chlorine removed during the process of sanitizing.  The amount of organic and non-organic material contained in the water will demand a certain level of oxidizer to be destroyed.

CIRCUIT BREAKER:  A switch which allows manual override of an electrical circuit.  It also automatically breaks the circuit when current fluctuations are detected.

CIRCULATION SYSTEM:  The circuit of plumbing which continuously carries the water out of the pool, through the pump and filter then returns it to the pool.

CLARIFIER:  A clarifier is a chemical used as a coagulant of suspended micro particles.  It helps the filter by clumping smaller particles into filterable sizes.

COAGULANT:  The properties of a chemical used in the assemblage and precipitation of suspended material which may make the pool appear cloudy.

CONDUITA pipe, usually gray PVC or flexible PVC designed to carry wires from a source (i.e. time clock) to a load (i.e. pump motor).

CONTAMINANTS:  Any micro-particle or organism which reduces water clarity or quality and may present a health hazard.  All of our filtering, circulating, and sanitizing is directed here.

COPINGThe capstone on top of the bond beam which finishes the edge around a pool or spa.  It may be pre-cast concrete or brick.  On vinyl liner pools pre-fabricated coping is usually part of an integrated system for the wall, vinyl liner, and deck.

COPPER:  An effective algaestat and algaecide.  Copper as elemental is used in many pools in products like "Pooltrine."

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 Cyanuric Acid (CYA) or a stabilizer, this chemical provides a shield from the sun around the chlorine molecule, extending the efficacy; saving you money.

CORONA DISCHARGE: An electrical discharge brought on by the ionization of a fluid surrounding a conductor, which occurs when the potential gradient (the strength of the electric field) exceeds a certain value, but conditions are insufficient to cause complete electrical breakdown or arcing.

CORROSIONThe effects of a acidic pool environment.  One in which the pH and/or alkalinity are very low.  Corrosion in the form of etching, pitting, or erosion of pool equipment and surfaces is the result.

COUPLING:  A plumbing fitting designed to join two pieces of pipe.

 

COVER AUTOMATIC:  Solid reinforced vinyl which rolls onto a reel on one end of the pool and attaches on the sides into small aluminum tracks.  It can be be motorized or hand-crank style.  Some models may snap the sides into small anchors placed into the deck providing more shape flexibility.  Provides safety (with water pumped off - cover pump), debris protection, and heat/chemical/water retention.

COVER HARD:  A cover which rests on the edge or coping of the spa or small pool.  Provides a barrier to debris and possibly people, while keeping the heat trapped in.

COVER SOLAR:  Sometimes called a thermal blanket, this cover floats on the surface magnifying the sun's rays to warm the water and also prevents chemical/heat/water evaporation.

COVER WINTER:  A barrier to sun and debris, winter covers secure the pool from contamination.  These are subdivided below.

COVER MESH:  These stretch tightly across the pool like a trampoline.  They are the only covers which can be called "safety covers" in that the mesh polypropylene allows precipitation to pass through.

COVER SOLID:  These are usually made of some form of plastic or vinyl and are secured around the edges either by aqua blocks, similar weight, or the edges attach to anchors set in the concrete or wood deck.
