Ozone Use in Marine Aquariums

Leave a rating

Ozone, (O3) has the same elemental composition as oxygen, (O2) but very different chemical properties. Ozone, (tri-atomic oxygen) is a very unstable molecule. It is a powerful oxidizer. When ozone comes in contact with a compound exhibiting an “oxygen demand”, it releases one of its oxygen atoms resulting in the formation of an oxygen molecule, with the third oxygen atom becoming attached to the now oxidized compound.

Extremely detailed. Very easy to read and after using Ozone for almost 1 year... I think I understand it a lot better now! I never thought O3 could be used "continuously" on a reef tank and that the actual position of the unit setting knob could be precisely adjusted.
