Acid - A chemical substance that contains hydrogen. It is used to lower the pH or neutralize the alkalinity in
Acid Demand Test - A test made together with the pH exam that helps determine the exact amount of acids
needes for optimal maintenance of pools.
Algae - Microscopic plant like organisms that have chlorophyll. The algea can be transported by rain or wind.
They thrive by the intake of carbon dioxide. Algeas grow in colonies. Algeas do not cause diseases, but they
can promote bacterial growth. There are more than 21,000 species of algeas. The most common pool ones
are green algea, blue green algea, mustard algea and black algea. Pink algea or red can also be found
but they are in effect bacterias. Proper maintenance of pools helps prevent and destroy algae.
Algaecide - They help to kill algea. They control the airborn contaminants that get into pools. There is a large
variety of algaecide products.
Alkali - Tambien recognized as a base. It is the opposite of acid and it helps increment the pH or alkalinity of
Ammonia - Compound that gets into pools by swimmers waste( sweat or urine). It mixes with the chlorine
and forms chloramines which have a foul smell and harmful to our health.
Bacteria - These are los unicelular microorganisms that are most danerous in pools. They can cause
infeccious diseases. They are controlled with disinfectants and sanitizers.
Bactericide - Kills bacterias. Chlorine is a bactericide.
Balanced Water - The effect of when all the chemical parameter in the pool water are within acceptable
Base - Chemicals that are of alkaline nature. It is the opposite of an acid.
Bleach - Liquid chlorine. the chlorine in pools has 12% to 15% of chlorine while the chlorine used at
households only has 5% chlorine.
Blue fingernails - This is caused by an excess of copper in the water. It can be caused by the use of cheap
copper based algaecides.
Bromamines - By-products that form when bromine reacts to swimmer waste (urine or perspiration),
ammonia or nitrogen. They may not have a smell. High levels are harmful to health.
Bromine - Used as a disinfectant or sanitizer for pools.
Capacity - The amount of gllons of water that your spa or pool can hold.
Clarity - The transparency of the pool water.
Chloramines - Components that have a foul or smelly odor that form when there are low levels chlorine and
these come in contact with nitrogen or ammonia that comes from the perspiration or urine of swimmers.
They are detrimental to a persons health.
Chlorine - It is used in liquid form,granulated or in tablets..Se usa en forma liquida, granulada, o en tabletas.
Cuando se anade al agua, actua como un oxidante, desinfectante y un sanitizer.
Contaminants - Organismos or microparticles that reduce the quality of the water, the clarity of the water and
present several types of health hazards.
Disinfectants - All of the elements, processes and chemicals that are used to destroy contaminants and
microorganisms in the water.
Enzymes - Used in commercial pools to break down and destroy the accumulated oils in pools.
Fill Water - Water that is used in filling off the top of a swimming pool. This watr has its' own chemical
Filter cycle - La cantidad de tiempo donde el agua fluye por el filtro. Se expresa en cantidad de horas.
Filters - Mechanisms or devices that remove the suspended particles in the water. There are three main
types of filters; sand filters, cartridge filters and D.E. filters.
Foam - Burbujas on the surface of the water. This is caused by creams, oils, or other contaminants in the
water. Enzymes are used to control them.
Green Hair - This is a condition caused by high levels of chlorine in the water or by too much cooper in the
Hard Water - Water that is high in salts, calcium or magnesium. It causes scales to form around the rim of
Iron in the Water- Can cause the pool to seem to be "light brown". Can stain your pool.
Microorganisms - The purpose of all disinfectants and sanitizers is to destroy these extremely minute
creatures that live in the water.
Nitrogen - A gas that causes algea to develop in the water. Nitrogen is introduced in the water by rain and
even by swimmers.
Organic Waste - Everything that could be introduced into the water by swimmers. os banadores. This entails
deodorants, lotions, oils, natural body oils, sweat, spit and urine. Organic waste also refers to all the leaves,
dust and insects that enter the pool. All of this waste may cause the undesirable chloramines in the pool.
Pathogens - Organisms that live in the water that may cause sickness and even death.
pH - It is the logarithmic expression of Positive Hydrogen Ions in the water. It indicates the acidity or alkalinity
of the water. A pH of 7.0 is neutral. A pH above 7 is alkaline or basic. A pH under 7 is acidic. The ideal
parameters of pH for pools is between 7.0 to 7.6.
Sanitise - When all of the contaminants of the water are eliminated, including microorganisms, bacteria and
Scale - When there is too much calcium in the water or the pH is too high. Scale appears gray o white.
Skimmer - A net used to remover leaves, flowers, or other objects from the pool.
Sediment - The solid materials that are deposited at the bottom of the pool.
Soft Water - Water that has very little calcium or magnesium.
Superchlorination - When we have added 7 to 10 times the normal dosis of chlorine to the water in order to
destroy the chloramines, nitrogen , ammonia, and any other contaminant in the pool.
Turbidity - When the water does not appear clear, it can be caused by a serires of problems.
Virus - Pathogens that are capable of causing sickness.
