True, but at least the picture would look better. My zoa's and star polyps DO NOT like the diatoms at all. The zoa's only open up 1/2 way and the star polyps barely even try to pop out. I keep them cleaned off frequently with my turkey baster as well as my LR. The sand bed still looks like it is trying to turn brown. Diligence seems to be helping, but too soon to tell yet. I will let you know how it goes.
