let me start out with my tank parameters 90 gallon RR 125lbs LR

S/G 1.025
temp 79.6
ammonia 0
nitrite 0
nitrate 2ppm
calicum 410ppm

this is a tank that I setup 6 weeks ago. Up until this week algae has not been a problem. What I did this week is I cranked up my T5 day bulbs, before this I was only running my blue actinics for 4 hours a day. BTW this is my first reef and I have never had a lighting setup like this.

The live rock has no algae growing on it to speak of its all on the glass and is getting a good coraline bloom. Everyday there is a thick film of browish/green algae on the glass. I know my flow is low in the tank as of right now I only have about 6x turnover I am adding 2 Koralia 4's this weekend which should fix that. What do you think I need to do to battle this algae bloom?

I also am using RO/DI water that's testing out at 0 tds
