I have a little issue that I didn't know I have until I saw another tank, everytime I look at my tank there's always little debris flying around, not a lot but enough to see ,always thought it was normal but looking at someone else's tank noticed it wasnt like that, the only difference I see is that he had a filter sock on his return in sump and I do not, I just have one of those flat white/blue filters in there, is this my problem? Btw my substrate is crushed coral so I don't believe it's too fine.
