Coralife MH bulb quality

[Kryten]

I've also noticed that my Coralife 10000K pc bulb looks more yellow than my other one by Hamilton - both very close to the same age - and the Hamilton was cheaper!

i've only had my coralife 10,000K 150watt for a month now, and seems to be giving a strong yellow tint. could this be the reason for my recent boom in green algae growth?

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.

yeah this really makes me wonder...
I have had my tank up and running for just over a year now, and have NEVER had any hair algae or any nusance algae until now. It grows quickly, I use my magfloat on the front of the tank, and I'll NEED to do it again in 3-4 days.

I am more than happy with the setup, and design, but it seems odd that the bulbs provided dont seem to be of the same quality.

Looks like I might swap my 10000k bulb. Any suggestions on which is best? I'm thinking either another 10000k, or 14000k.
