Funny you mentioned that - I was think the same thing last night. Im on my second month of running these bulbs and I am getting a ton of green algae growth - Am I have NO fish just corals, clean up crew and an arrow crab and I am not even feeding my tank. Seeing the results reminds me of what happend when I tried using flourecent plant grow bulbs on my first reef

With my older 240 Gal setup that had about 150 Lbs of LR, softies and two horn sharks (huge bio load) I had NEVER experience ANY hair aglae blooms over the few years it was running, just the odd 'tuff" that I brushed off with a tooth brush. I was running 2 175W Hamilton 10000K lights at the time. NOW with just about no bio load and CORALIFE bulbs Im getting HUGE amounts of hair algae. BTW the rest of the system design is the same as my last setup.

WHATS UP WITH THESE BULBS

Soory to go off the handle, but I am a little ****ed that in order for these lights to perform relative to the high price they command, you need to spend an additional $150-200 to get bulbs that at least put out what they are intended to.
