The Hydrogen Sulfide is being caused by anaerobic decomposition of organics in the peat. You need to keep "dead" (anaerobic) areas from forming in the the peat layer, just like in aquarium gravel. Either use a thinner layer of peat, stir the peat periodically, or make sure that oxygen reaches the bottom of the layer of peat. I wonder if an old under gravel filter plate might work?? You can drive some of the H2S out of the water by aerating it. Being heavier than air (O2, N2, CO2, etc.) it might be harder pull it out of aqueous solution, however.
