my tanks going well. my 1st marine experiance is turning into a good one. i have a questions though regarding fish waste, and substrate vacing.
fig1. to me looks like the build up for fish waste yes?
fig2. again a whole pile of it? is one of the fish collecting it?
i know your not suppose to gravel vac marine tanks but what am i supose to do about this what looks to be fish waste issue, carefully gravel vac? or will something living feed off of this? i've got 3 turbo snails in my tank but they are focusing on the algae..
what should i do ?
