Checked on my tank before work and noticed that my chalice in whiter than usual in the middle. Ther also arers to be some brown algae looking stuff sitting on top of it. I did't have time to take a pic or test water, but really worried about my new piece. Been in the tank just under a week, and last night I was looking at it under the actinics watching the sweepers. This morning that center area has no flourecence like it did just 12 hours ago. Could a temp drop or a ph spike cause this? I just started dripping some new kalk the other day.
