I think the subject says enough. Is there anyway to slow this down, the algae is purple, dark and starting to cover everything. Its growing over the coraline algae.
I know this sounds extreme but i had the same problem with the purple slime algae at my work and at friends. I was at wits end no phospahtes or nitrates. I even used a phophate sponge and it did nothing. But out of the blue i decided i would try CYCLE and for some reason the algae disappeared and it hasnt been back. It worked on two tanks i thought i was going crazy. Anyone else have the same experience? I never thought it would do a thing. I usually dont go for MIRACLE CURES but what do you know. It is just a sugestion, you may want to chech phosphates though just to see if that is were it is coming from.
Hmm, this is macro algae. Maybe cause you had slime your tank was still cycling or going through a mini cycle? Im not sure that would help me as it would feed the macro algae.
