Well I was awoken by a horrible smell. It was my tank... it crashed during the night. The only thing I can figure is hydrogen sulfide poisoning from the bio reactor. I pulled as many fish as i could and dumped them in fresh water then dosed the tank with h2o2. My solar wrasse is for sure a goner. He is just twitching. Likely will loose my mandys and ruby red. My regal tang is not looking well either. [emoji31]
