Christy...I have some, but very little, of the brown wafer algae. I'll keep an eye on it for you
This valonia is breaking my heart, though. Ugghh! I'm testing zero nitrates and zero phosphates consistently. Water changes, blah blah blah....nothing seems to phase it. I could continue to remove it manually (and I will), but I'd like to see if this makes any difference whatsoever.
I've also started programming my lights to go off for an hour in the middle of the photoperiod (a little trick I learned on the zeovit forum website), and I think it might've helped a little already.
