I just covered the red LEDs on my multicolored (reefbreeders) fixture, because that's the only part of my system where I have algae. Cyano and some thick brown stuff is all over the sump with the rb fixture over it, but the rest of the system including the DT is spotless now, with just the straight blue and white units.

I don't think those few red LEDs have anything to do with the algae. Granted, red is just as powerful for photosynthetic processes as blue spectrum (both in algaes and in corals that use Chlorophyll A). But you have so few of them. A real test would be to switch the fixture to another algae free tank and see what happens.

How can blue LEDs stimulate photosynthesis and not grow algae as well as a red LED? Nuisance algae isn't selective to a certain frequency IMO.

I just covered them and the color difference is drastic. There are only two. Give it a few weeks and we'll see. I would not want to switch the fixture because I don't want to shock any corals anywhere throughout my system with a light change.

I just bought these. I hope they are good. It says that the LED chips are bridglux or Cree. I will let you know what I think of them. http://bit.ly/14DmE6E

We go back and forth on this and frankly I don't have a hardened position on it. I like the look of my Rapid full spectrum fixture, but I also like my white and blue Chinese fixtures, both grow coral well and the color difference is a matter of individual preference.

Price was right. Don't understand the Cree or Bridgelux "chip" comment. Seems kind of weird. It looks like Bridgelux LEDs are shown in the pictures. Crees are usually considered more efficient, but depends on the part number. If you don't like the red, you can turn it down.
