Well. As some of you all know I just put a dragon wrasse in my tank. And this thing is kicking up a lot of sand. Now the problem is i stoped cleaning my sand(with the gravel vack) after I had no more algea growth on it. every couple of minutes this guy kickes up some sand. And with my fluval 304 and protien skimmer its jsut now enough to keep the water nice and clear. I was wondering if I could put little foam covers over the intake on my maxi-jets?/ waht do you guys thing about this, thanks..
