Algae—What You Should Know

Ozone Does Not Kill Algae!*

Why Doesn’t Ozone Kill Algae?

• Ozone is destroyed immediately when it makes contact with any

oxidizable substance in the water. How? Ozone is very reactive - it

is oxygen with an extra oxygen atom hanging on. When the ozone

hits something (could be a virus, some bacteria or suntan lotion), it

releases an oxygen atom (O

) and creates an oxide of that material.

All that is left is a molecule of oxygen (O

). Because ozone is such

a powerful oxidizer and will oxidize matter so quickly, it is gone

almost as soon as it is formed.

• Most of the ozone is destroyed upon mixing with the water at point of

injection. What’s left will be consumed soon thereafter. Very little, if

any, ozone makes it into the pool water. Any ozone that does make

it into the water has a very slight chance of making it to the wall

of the pool or spa where the algae grows.* If it actually makes it

to the algae, it is so diluted that it cannot destroy the algae (algae

that travels directly through the ozone injector does have a chance

of being killed).

Conclusion

Ozone is not a stand-alone sanitizer. Residual levels of chlorine

(0.5-1 ppm), bromine (1-2 ppm), must be used to inhibit algae

growth (see page 26-27 for the perfect combination).

*In large doses with a long contact time, ozone can kill algae, but it is very unlikely

in a residential application.
