Re: [APD] hydrogen sulfide - thanks

O2 levels probably won't significantly affect how much
hydrogen sulfide gets into the water. But aeration, even
(or espeicially) if done with a power head that moves lots
of water to the surface, can help to off-gass the nasty
stuff about as quickly as it enters.
