Need help corals are starving :(

[JMLewis]

A little back story:

Started my tank almost a year ago, everything was great and dandy sps growing great, awesome color etc. About 2 1/2 months ago I added a new fish without quarantine (broke my own rule) and it had velvet and wiped out all of my fish including a yellow tang and chevron. The only fish to survive was my Leopard wrasse which I moved into quarantine.

Within about 2 weeks of the fish dying I had a major hair algae outbreak. Apparently my fish were keeping it in check and now they were gone the algae went nuts. I've been doing bi-weekly water changes and pulling out as much as I can with every wc. To only have it grow back, it's way slower to grow now that there haven't been fish for 80 or so days now.

Anyways I'm not sure how to keep my corals from starving without making my hair algae go nuts again. I've added turbo snails, gone through 3 sea hares, none will eat it to keep it in check. I'm at a loss....

Am I just screwed? I've been adding AA but I feel like the algae is just sucking it up before the corals can benefit from it. What can I do?!?!

Here's a few pics.

Not hair algae as far as I can tell, it looks like Chrysophytes to me, a silicate type of growth, but some say it's a form of Dinoflagellates. Regardless it seems to be toxic. If you're using any egg crate get ride of it. Stop adding any amino acids, feed the corals as you would normally feed fish, Rods Foods or similar frozen brands. Thus far I have not heard of inverts that will eat it. Treat it as you would Dino.
