Pool Sanitizers


When most people think of what keeps their pool sanitary, the first thing that comes to mind is chlorine; but that is only one of several different approaches. Here is a rundown of the pros and cons of several of the most common types of swimming pool sanitizers.


• Easiest to use of all sanitizing systems
• The oldest and most popular form of sanitation for pools and spas!
• Chlorine oxidizes, thus removing electrons from microorganisms making destruction of bacteria much easier
• Comes in various forms; liquid, tables, sticks and granules

• Creates chloramines which lessen the sanitizing power of the chlorine
• Chlorine has a rapid burn off rate (every 35 minutes of sun, chemical loses half it’s killing power)


• Bromine is effective in hot temperatures which makes it a great system for spas

• Loses 65% of killing power after only 2 hours in the sun
• It does not oxidize and therefore requires a separate oxidizer to break down and kill organisms


• Attracts bacteria
• A very gentle sanitizer making it great for vinyl-lined pools

• Does not oxidize and requires a separate oxidation system
• Attracts more and more bacteria making the molecule larger and larger which in turn means less application of the chemical, but also means more work for the filter resulting in more equipment maintenance


• Chemical Free
• One of the strongest and most rapid sanitizing and oxidizing systems
• Combats microbes that have become resistant to conventional sanitation systems
• Can oxidize inorganic and organic compounds

• Does not combat algae so chlorine is typically used in conjunction


• Requires little chlorine usage
• Copper and silver are used as they are toxic to bacteria in an ionic state

Catalytic Sanitation System

• Uses oxygen molecules to kill microorganisms similar to the Ozone system
• Requires little chlorine

• Does not combat algae
