i know how it is, it can over grow everything, when my tank was about 2 months running my hair algae got so bad i couldn't even consider any more corals, so i tried that scalding water in a water bottle procedure, and i did that maybe 3-4 times followed by a couple 20% water changes as albert dao recommended and since then i've been nuisance algae-free for 5 months, no hair,bubble, or plate algae. you might want to try it out- i got it from michikas hair algae thread a couple months ago-
good luck-
