hair algae during cycle

[JDigital]

^^ EDIT: Trigger beat me to punch...

Running your lights will give the hair algae something to feed off of, as it is photosynthesis, that's why when you cook live rock with algae and other nuisance problems it is recommended to have a completely lights out environment... Your tank will cycle just fine without lights. Once your cycle is complete, continue to do a week or two of water changes without lights, and then you can start increasing your photo period (ie: start @ 4hours, then 6, 8)

Blasting a tank with high levels of light all of sudden can cause a big algae bloom (as I found out when I added about 200% increase on my FW tank with some T5HO's on the same photo period as the stock 15W bulbs) hahaha.. the tank was GREEN... glass, substrate, decor...
