50 yr of keeping saltwater, yet my 1st sump. so, I,m running a mag 12 return, a mag 9 for the skimmer and a mag 3 for the fuge. I also have 2 wave's in the tank, I,m running 5 deg f above a tank with no sump. so, does this sound normal.? I assume this is from pump heat. there are no heaters running at this time. also after about 1 month I see a little coating of debris? in the bottom of the sump. how does one remove it?
