Bad Hair Algae

[Matthew N]

I had that exact same problem, so I know what it feels like.

What seemed to be my problem was phosphate, I started to use RO water from the local grocery store and that helped alot, but at the same time it seemed to hurt coral growth which I thought was weird.

So I mixed half and half (well water and RO water) and that made a huge difference, I also increased my lighting to 120 Watts, because I noticed the hair algae was bleaching that was closer to the light, This seemed to clear all the hair algae out but the red slime started to grow like crazy.

I then bought another powerhead, and that seemed to take care of all the red slime.

Oh and I also started to pour tons of seachem's reef complete which raises calcium.

I live on the east coast so my make up water might be different then your's but I really hope this helps
