You don't remember which page number it is on do you?

thanks. Well time to go home now.... Sure has been nice that the boss leaving early can catch up on my reading... LOL

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

 

[Gregcoyote]

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.

That's what it says on the auction.

I know, I saw that and still don't understand.

 

[Gregcoyote]

If you have a choice, I would go with Cree.

I just asked the guy. Waiting for a response. What is the big difference between the two?

My T-5's are doing the same to my sand bed. Cyano on it if I have the lights on to long and I only have the white and super actinics on it.

I asked about the Crees when I bought mine. I was told the didn't have those in stock at the time. So more then likely it's not Crees.

 

[Gregcoyote]

They'll still be okay.

 

[Stlrockguy]

I'm about to buy another one since I'm getting a 150 gallon on Sunday.

 

[mr_X]

If you are buying the 150 new, go with the 180. It's a much better footprint.

 

[Stlrockguy]

I'm buying it used. I want a 180 but can't find a decent priced one anywhere. The 150 is a more then I wanted to spend. But the dimensions are 72x18x27. So I'll have my 6 footer
