Algae Problems, Blah.

[Travillion]

Hey guys,

I know there are a ton of algae posts, but generally it is because of new tanks, high nitrates, lighting, non-regular water changes, no CUC, etc.

So here's my problem. I have a nasty case of hair algae that just won't quit, and I cannot figure out an explanation. I want to stop it, and rid my tank of it before it's too late.

My 28G tank is over a half year old now, and completed it's cycle about a month in. It's diatom stage came and went, then the algae came, and eventually started to diminish. However it never fully went away. It's main point of focus is right on my live rock, which is the very porous pukani rock. It gets right into the crevices.

My CUC consists of astrea and turbo snails, hermits and an urchin. I swear these guys never even touch the algae on my live rock. They've done a good job with keeping the glass clean, but nothing else. **My tank is bare bottom, so I did not feel the need for nassarius and other sand bed critters.**

I run an RW-8 along with the included pumps for circulation.

I have a TUNZE 9001 protein skimmer and filter foam (rinse out daily) for filtration.

Maxspect Razor 60W 16K lighting that never goes over 80%.

20% water changes weekly using my own RO/DI unit. TDS readings at 0.

Nitrates: 0

Nitrites: 0

Ammonia: 0

All I have for fish are two young clowns and a six-line wrasse, certainly not overfed.

Lots of softies and LPS that seem to be doing well, though my zoas and paly's haven't had much growth

I am probably forgetting to tell you guys something, so please just ask me anything specific and I will be able to answer.

Any help is strongly appreciated.
