In a weeks time nitrates get to twenty or thirty mabe but a five galon wc brings them to zero for most o the week. Got several kinds of red alge none of it slime i dont think, and alot o green alge. All my coraline purple/ pink alge went real pale too. It happened over time so i was lookin at old pictures when i noticed how drasticaly different it looked. The red velvety stuff seems to be growin on my green stars and killin some of it off. Got a few pics might help some. First one is the velvet lookin thick stuff thats on my stars.
Here is some of the green all over the back wall now.
This red is hard and apears to grow like hard coral almost, its grown out away from the rock these pink stars are on.

Any info or suggestion appreciated, thanks!
