Since everyday cleaning is next to impossible, the various types of pool chemicals help break down dirt in your pool water and keep the it free of bacteria, catching things your skimmer can’t. But sometimes the names of pool chemicals can be confusing. Here’s the low-down on the different types of swimming pool chemicals and what they do:

• Chlorine – This most commonly used pool chemical is brought in to help keep bacteria at bay. Without chlorine in the pool water, your swimming pool would be a breeding ground of bacteria, mosquitos and other pests.
• pH Reducer or Enhancer – By their names, you can already tell what they do. The pH reducer is important if you have hard water in your area. Hard water contains minerals that create buildup, such as calcium and magnesium. If soft water is a problem in your area, you’ll need a pH enhancer, usually an alkali, to neutralize the water.
• Algaecide – Algae builds up in any water, moving or stagnant, and usually forms along the sides and bottom of a swimming pool. An algaecide keeps algae problems to a minimum.
• Flocculants – Some dirt in your pool is microscopic. Because of this, it’s hard to remove them all without the help of flocculants. Flocculants work by acting as a binder, causing the small particles to clump together, become larger and thus easier for your skimmer or filter to catch them

Whenever you’re using pool chemicals, make sure that you take the necessary precautions in keeping yourself and your family safe. Adhere to warnings and precautions made by the pool industry, and test your pool water regularly to maintain the right balance.
