5 Reasons Hydrogen Peroxide Is a Bad Pool Sanitizer

It breaks down too fast in sunlight and heat You would need to add gallons every day to maintain any sanitizer level, and it still does not last.

It does not control algae or bacteria well Hydrogen peroxide is far less effective than chlorine or bromine at killing common pool contaminants.

It requires constant testing and dosing You will test and add chemicals repeatedly, yet still end up with green water.

It fails as a primary sanitizer Even when used as a shock or in a non-chlorine system, it is unreliable and causes headaches.

Chlorine is cheaper and more reliable Chlorine works, costs less, and requires far less maintenance than hydrogen peroxide.
