I'll just add this point, all the large public aquariums use ozone for delicate fish.

Granted they can't use chlorine, but ozone is the choice in these hi-tech systems.

If you still need to add chemicals with ozone, you have the wrong size ozonator installed.

Saltwater alone is still growing many types of bacteria and algea so it's not the total answer, but you can add ozone to saltwater.

Saltwater fish tanks use them.
