What kind of lighting do you have? And how old are the bulbs? How many snails do you have in there?

I have a 36" T5 light fixture. Bulbs do need to be replaced as they are a 1yr old. Snails... a good question. I can't even keep them alive. No matter how many I put in the DT they don't last. I have a bunch of baby snails in the sump and have been adding them to the display.

What do you have in the DT that are eating your snails? I find a good crew of astreas and new bulbs to work wonders for a bad case of HA. I had a problem with HA with our 65 because of the inhabitants. They ate the snails, but whenever I'd replace them (and the CF bulbs) the HA would go away.

The reference to Magnesium has to do more with bryopsis than standard HA as HIGH mag kills bryopsis like nothing else I've seen.

Phyl,
Wish I knew what was eating/killing the snails. No crabs or large shrimps to my knowledge. I have a brittle start that is black and gold colored. Hides in the rocks and only sticks out arms when I feed the tank. Very hard to get a pic but will try.

This is a similar looking sea star. Just that mine is yellowish where the white is.

Flame angel

Cardinals
Perc clowns
Striped psuedochromis
Lawn mower blenny

I will mention this although have never seen it.
Twice my son has seen something red colored coming in/out of a rock. He said it looked like a Triops.

Did you get a phosphate test? Hair algae essentially thrives on three things: Light (especially old bulbs), nitrates, and phosphates. You can't elimnate the light all together but you can decrease your photo period and change the bulbs. Nitrates can be reduced through less feeding and having good filtration. Phosphates can be removed with phosban/chemipure.

If you increase your flow or turkey baste your rocks pretty regularly "stuff" won't settle on the live rock and helping the algae grow.

My 12g looked like your tank for a while so I decided to get serious. I added a powerhead, put in new phosban and carbon, cut back on feedings, blacked out the tank for a day or two, and scrubbed that evil hair algae right off. Since I put everything back in I have had no new growth of hair algae and the spots that I missed from the scrubbing all died off.

I do run a Phosban reactor and occassioanlly add carbon to it, out right now. I am considering scrubbing the rocks although I really don't want to. I feed every other day and a little at a time. This way the fish will eat most of the food and little is lost to the crevices.
