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.

Chlorine

Pros
• 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

Cons
• 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

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

Cons
• 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

Biguanide

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

Cons
• 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

Ozone

Pros
• 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

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

Ionization

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

Catalytic Sanitation System

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

Cons
• Does not combat algae
