My power heads have inadvertently caused a corner of my tank to be a DSB. And my chevron tang likes to take his dumps in one corner and obviously sand gets blown on top of the poop and now about a month later the corner is completely black (metal sulfide? Hydrogen sulfide pocket?) obviously the area is probably anoxic, but the lower layers are not black. The black is probably the trapped waste and has become the hydrogen sulfide/byproducts?
Anyway, I need to siphon it out and just remove some of that sand, but any harm in doing so? I’m planning on siphoning that whole area out, but I’m worried cuz my tank is thriving right now and all my acros are making me feel like I’m blessed. Don’t want to kill anything.
Advice? I only have sand cuz I used to have a lot of leopard wrasses and now have one.
