Ok I was cleaning out my sump today and noticed a few of these little son of guns stuck to the glass near my filters. They came off very easily and I didn't even pay any attention until afterwards when I actually looked at them ;Pompus and saw they were all the same exact size and shape. What in tarnation are these things???! And why only on the glass in the sump and not the DT? They don't move so idk if it's a type of detritus or bacteria but I had about 10 of them just chilling down there and they freaked me out. Please tell me aliens haven't invaded my sump ;Vamp
