The whole H2S thing is blown out of proportion too much. Unless you have a deep sand bed (4+ inches), I wouldn't worry about that.

exactly ive disturbed more sandbeds then i can count and ive never caused any harsh damage.if a tank gets ample flow and has something like a star or goby to keep the sand moving then i wouldnt worry about it.


my tank is 5yrs old and i just did this to no harm:P
