Dissolved O2

If you have a protein skimmer (venturi) you can run the air line outside to avoid indoor CO2. I did that and it helped, but............after much research the only true way I found to raise your ORP level is to inject ozone.

It is a much more complex setup than I originally thought but am currently waiting for my Ozone reactor to arrive.

If you are interested I can share what I have recently learned about ozone and the setup..........

Thanks. I have been having trouble with fish dying. Corals are fine and growing. I have clams and they are healthy. I'm trying to figure out the reason why my fish croak.

Salifert makes an oxygen test that seemed to work for me. That might let you know whether oxygen is the issue. Do the fish show signs of gasping?

No. But looking in the tank I found some red algae/cyano bacteria on the backside of some rocks. I wonder if that could be the culprit
