LED chaeto/scrubber lighting

[Wes]

I've seen mentioned in a few places that red spectrum lighting(660nm) is best for algae scrubbers. I've had fine luck with CFL (warm and cool white), but I'm thinking about buying/putting together a cheap LED fixture for the fuge area. I'm not sure if I'll stick to chaeto or eventually build an up-flow algae scrubber, so I'd like to get something that could grow both.

 

Basically, all I'm asking is if anyone has advice on growing chaeto under a red LED.

i would just use 6500 lights. it works for both.

I've grown chaeto under 3500k CFL bulb really well. and now I have the fuge PAR38 light from RB and I would say the chaeto grows faster with it. there's more red spectrum in the lower Kelvin temperature bulb so it'll work better with a 3500k than a 6000k and the 660nm being the fastest bulb for growing chaeto, in my experience.
