Around 3-4 months ago, I experienced one of my worst hair algae and cyano outbreaks with my 1yr old reef tank. After fighting it for a good month, I pretty much gave up and gave away most of the livestock except for a few mushrooms, a false perc and a few snails. For the past 2 months or so, the light was not turned on, feeding was down to once a week and as of now, most of the hair and cyano have died off.

Knowing that I pretty much have to start from square one, my question is, will these things grow back immediately? Some of my snails and crabs have died in this process as well, and I'm planning to get new hermits to hopefully feed off the remaining hair algae. Please gimme some of your opinions and advice.
