Twice now in the last month or so I've had an occurrance where the water in my tank gets cloudy and there are hundreds-probably more- of tiny(about 1mm) round, white objects floating through the water. Has anyone had this happen to them? I'm guessing it's my large Colt coral because they seem to be coming from there. It could be that they just got stuck but none of the other corals have as many or any at all.
