Easy Guide to Pool Chemicals

pool water chemicals

Pool chemical usage is very important. The levels have to be accurate, so the water quality is safe and healthy. Anyone who is not an expert in pool maintenance like pool service in Gilbert might find the vast array of pool chemicals to be a bit confusing though. So to help make understanding them a little more simple, the following is a guide discussing some of the basic chemicals used the most.

Chlorine and Bromine

These two chemicals are both sanitizers. Chlorine is very harsh to the hair and skin, but it costs half as much as bromine does. They are both important for clear water and the prevention of diseases caused by dirty water. The recommended levels of chlorine for swimming pools is 1.0 to 3.0 ppm.

Adjusting pH Levels

pool water pHThe optimum pH for pool water is 7.4. If it gets above or below this. it can cause algae to grow out of control. The water will also become uncomfortable to be in because of the irritation it can cause to skin and eyes. There are chemicals that can be added to change the pH though. They are called pH increasers and pH decreasers. Always add them a little at a time because too sudden of a change in pH can cause more significant water problems.

Cyanuric Acid

This is a chlorine stabilizer. Without it, the chlorine would dissipate very quickly from the heat of the sun. Some pool chlorine tablets have it in them already. Its levels should always remain less than 20 ppm.

Stain Removers

Water contains metals and organic material, which can lead to stains developing on the walls and floor of the pool. Some of the stains can be reduced with scrubbing, but for those that can’t, special stain removers can be used. The kind of stain remover depends on what the source of the stain is though, and the best way to tell is with a water test.
