Ok, besides Phosphates being too high which I am fighting now with water changes, GFO and Lathanum Chloride is it possible that my very old metal halides are causing a really strange fur like algae to grow on my rocks. I don't call it hair algae because I have some of that ins some rocks but not too much. THis stuff almost looks like it a cacoon of some sorts developing all over my rocks. It's furry algae but not very green kind of sand color with a bit of green. Some spots are starting to develop bubbles.
I'm just wondering if my old lights could be causing it. I've been waiting on Reef Radiance lights since my order Sept 23.
