I do not want to give up, but I cant beat hair algae. Let me give you some background first.

Here is my tank:

75 gallon reef with 2 inch sand bed
protein skimmer in sump
fluvial 304 canister with no media in it to lower nitrates
1 power head and 2 out flows from fluvial and sump
20 gallon refugium, loaded full of Chato, with 3 inch sand bed
530 watts of light. 2 10k halides 2 power compacts
100lbs of live rock

I do weekly water changes 5% per week with RO water form the lfs.
5 fish, 1 is a yellow tang
2 emerald crabs, 2 conchs put 175 nasuirus snails, 100 turbos "astrrea" spelling

Tried:

every type of snail except mexican turbos
2 sea hairs - they disapear
lawn mower blenneys - they disapear
removed rock and scrubed it
phosate remover
conchs
hundreds of snails
Fox face

I did a complete cleaning and removed all the rock cleaned it, loaded the tank with turbos, and use the liquid phosophate remover. The tank looked great for about a week. Now all the algae is back. It looks like a carpet of algae all over the rock and some on the glass.

Most of the snails are gone, and pretty much all the turbos are missing. I put a cleaner shrimp in there and he is gone.

My water keeps testing good, my temp is 79 degrees, and I only use RO water from Plano Pets.

I seriously am about to give up. I do not know what the hell is going on with my tank. I can't beat this dam problem. I have been messing with it for 6 months.

Any thoughts?

Thanks
