I just changed from maxi jets (a 1200 a 900 and a 400) To 2 koralia 3's the tank seems to have a lot more flow but it looks like I have grey algae on one of my live rocks that was purple. is this just stuffed that was kicked up by the extra flow or something I should worry about. The tank is 6 months old and has had no other changes. It does not look like the diatom bloom I had after my tank cycled that was brown. This is grey.
