Swimming Pool Chemicals

Algaecides, Clarifiers & Enzymes


Most pool supply distributors can offer an astounding selection of algaecides for your swimming pool, and if you do not understand how they work or what each algaecide should be used for making the right choice can be difficult. An algaecide is either a copper based algaecide, or a "quat" or "polyquat" algaecide. Copper based algaecides use copper to treat and prevent algae growth, and can be used against all types of algae. Copper algaecides will not cause foam in a swimming pool, which may be a problem with the "quat" algaecides. Although they are effective against many forms of algae, copper algaecides can cause stains on the surface of a swimming pool if the product is not used properly. Copper algaecides cannot be used in a swimming pool using a biguanide based sanitizing system (such as Baquacil or SoftSwim).

The "quat" or "polyquat" algaecides are quaternary ammonium compounds with treat and prevent algae growth in a different way. These algaecides are safer to use than a copper based algaecide because they will not stains in a swimming pool. If you have experienced any metal staining in the past, you should use a quat or polyquat algaecide to treat your swimming pool. Although quats cannot cause staining, these algaecides may cause foaming if not used properly. Polyquats cannot cause staining or foaming, and are typically more expensive than the other forms of algaecides.


Clarifiers may be needed to help clear cloudy or dull pool water conditions. One cause of cloudy pool water is fine debris suspended in the swimming pool water, which is too small for the pool filter to remove from the water. This fine debris may pass directly through the pool filter and back into the pool. A sand filter provides the least efficient filtering of pool water, and this problem is more likely to occur in a swimming pool that uses a sand filter. A clarifier will group together the fine particles of debris into larger bunches, which are trapped inside the filter as the water is passing through. Most clarifiers cannot be used in a swimming pool with a D.E. (diatomaceous earth) filter.


A popular and highly effective enzyme based line of pool products has recently been introduced to the pool industry. These pool products kill and break down harmful organics in pool water using all natural enzymes, instead of harsh chemicals that can be unsafe to store and handle. When used with reduced levels of chlorine or bromine, these enzyme pool products are an important part of a very effective pool chemical routine.

Chlorine works to break down organics in pool water, but it's main function is really to kill harmful bacteria. If enzymes are used to break down all organic material in pool water, less chlorine needs to be present in the water focusing only on killing bacteria. Unsightly staining forms at the water line of most swimming pools, and is caused by the oils in the water. Oils float on the surface of the pool water, and combine with dirt or minerals to accumulate at the water line. The addition of enzymes on a regular basis will eat away at the oils, removing most existing stains along the water line of a pool or spa and preventing this ugly stain from accumulating again.
