Ozone Poisining ?
 

Is there such thing as ozone poisining ? Since I have installed my ozonator and ORP meter I have had a few unexplained deaths in my tank . I have it set at 300 .The lastest was a bi-color dottyback this morning. He was fine last night and I turned the ozonator on last night as well. I only have two other fish in the tank and they are fine as well as the shrimp . snails and coral . It happened two other times as well. 3 chromis fell victim one time and a Flame Angel the next. I'm at a loss of words .



Any ideas ?

How are you dosing your ozone? What size of tank and how many MG/hr are you dosing?

What did the dead fish look like? Any reddness around the gills?

Injected into my skimmer . 75 g tank & 20 g sump . . I have the ORP set at 300 . Fish looked fine . Was barely kicking this morning . Laying on its side and trying to swim . It eventaully expired. Sad to see . No redness really visable . Colors still bright, not faded .

Do you have the skimmer output going through some carbon to remove the excess O3?

Do anything esle to the tank recently?

I have the return from the tank going through carbon. Added some additives for the corals, but i always do that. I tend to froget to turn the ozone on.

Sorry, does this mean you have no carbon after your skimmer to absorb the O3? Just want to clarify.

Hmm, I'm not too sure what could be the case here. It doesn't sound like its the ozone though as everything else would be affected as well. To be safe, do the standard water change, run some fresh carbon and leave the ozonizer off for now.

Already turned off the ozone. I'll do a water change after work . Thanks for the insight, but damn, this is baffling.

Never mind killing your fish, be careful with ozone around humans as well:

What mg/hr are you running? What kind of ozonizer?

Read the RC links. Interesting, but may be dangerous for those competing for the Darwin Awards :razz:

This is a real question, though ....

Why does a reef need ozone?
