Algae

[krazykarl]

Hello I have recently started a Nano reef tank and have a small hair algae problem (I think). I have had the tank up and running for 26 days with 16 Lbs of live rock and 20 LBS of live sand. I was using tap water and have recently switched to RO water. I did a 15 % water change with the RO water and was wondering if I should also turn out the lights for two days or so.

Any suggestions.

Thanks
