this cloudy look is from bristle worms. I saw something last night that was really quite something. Also very very disgusting. I think what I witnessed was bristle worms spawning. 1 after 1 the were popping there heads out of the rock and spraying some white or creamed color cloudy stuff. My entire 160 gallon tank got so. Cloudy u could not see anything in it. It looked like the worst bacteria bloom ever seen. I did not get a pic because it was very late. I did check my skimmer cup this morning though hoping it pulled most of it from the water. So here it is.
