hair algae????

[wnecbubba74]

i got some hair algae growing on a couple peaces of my live rock and on the side of the tank. I've cleaned it up on the side of the tank but it grows back in a couple of days. What should i do about this? Do i need to do a water change?

Thanks

do you use ro water? how old are your bulbs? and what are your water paraments?
