Thanks for the reply Mike. I have very little circulation simply
because I don't have anything in the tank to block the flow, so it's just an
AquaClear 150 with only the sponge in the media chamber, and a sponge on the
intake. I do notice that there is a fine, fine white gunk in the sponge,
which I assume was the fine's from the crushed coral. But I did rinse the
coral substrate untill it was almost clear, but the instructions said to
NOT wash untill the water ran clear. I own a diatom Filter, so I'm going to
run that for an hour and see if it clears it up. If it does then I know it's
a particulate problem and not effects of cycling.
