Lighting and algae...

[SmallFry]

My new tank has been up and running for a while. I seeded the dry rock with a couple of rocks from the old tank. They are at the bottom of the tank. I notice that the coralline algae on the tops of them is pale now, or white. The hair algae on the rocks at the top of the tank (about a third of the way down) is not very green more like pale brown or white; fortunately there's not much of it either... The hair algae at the bottom is nice and green if hair algae is ever nice. Green star polyps growing like weeds at the bottom of the tank. There was also some weed or macro algae that was deep red in the old tank and it grew white in the new one. I say was because Truffles the sea urchin ate it..

Does this sound like I'm punching too much light into this thing? Lights are a DIY led array. 24 Cree XP-G cool white with 65 degree optics and 24 XP-E royal blue with 60 degree optics. I'm driving both channels at 700mA and the fixture is about 10 inches above the top of the tank. I've never done reef before or used anything more powerful than two 15W fluorescents so I have nothing to compare to and no idea how much light I need. The green star polyps are my only coral so far and they seem ok but I hear they're invincible...


Back to the hair algae again, does anyone have any suggestions for getting the stuff out of my green star polyps? I'm currently thinking toothbrush....

I'd appreciate any insight..
Thanks,
Rob.
