Rubble in sump/refugium


Premium Member
I am curing 150 lbs of live rock in my tank and I put 25 lbs of rubble in the sump/refugium. The 25 lbs of rubble was more than I expected when I ordered it and is piled up in the sump. Should I take some of it out so that nitrates won't build up or do you think that it will be ok? Here is a pic of the rubble in the sump/refugium. Jim
