So over the last 3 weeks Ive moved my tank i moved outta my parents house and as much as the old man wanted the tank to stay it didnt............ Id thrown my corals and fish into a 33 i had lying around and on Sunday finally got to the point of bringing the LR over, i got the rock setup and some new sand in im going with about 1/2" this time see if i like it better.

now my birdsnest had some hair algae in it and after 2 weeks in the 33 its covered ive picked off as much as I can but it still looks green.
Is there anything i can do to it to get rid of it? a dip in anything ?
I dont really wanna throw him back in my display tank all green
thanks
Kent
