Hey guys
I was messing around in sump/fuge, and i noticed there are two 5 inches patches of black stuff in the sand bed of the main tank( i was able to see through the glass of the display tank)
Is this sulfer/noxious gas build up? What si the best way to get rid of it? Should I stick my gravel vac tube into the sand bed next time i do a water change, and do a few on inch areas at a time? it is right under neath my two clams.
Any thoughts?
