Re: [APD] Hydrogen Sulfide?

A little hydrogen peroxide will destroy any H2S. You can add 10 mg/L H2O2 with no ill-effects on the fish or biofilter. I would keep it below 2 cups of household 3% H2O2 for your rainwater tank. Try 1/2 cup first and see if that doesn't get rid of it.

The water smells to me like hydrogen sulfide.  I expect that anaerobic bacteria in the water are making the H2S and I'm asking if anyone on the list is familiar with this.
