Refugium light.

Hey guys, I recently bought one of those RGB flood lights off eBay to use on an external fuge. The problem is, it resets itself to the original bright red colour when turned off and back on. It doesn't have a memory of the last setting used unfortunately.
This means if I put it on a timer, when it turns back on, it will be a bright obnoxious red light, not the nice 5000k I wanted.
Will a pure red LED still grow macros well? I know there's a photosynthetic peak in the red part of the spectrum, but will my future macros be lacking something if they only receive the red spectrum?

Bump.

I find it hard to believe no one has an opinion on an LED related thread!
C'mon guys!

Seems futile, but I'll bump once more.

Pretty sure the scrubber I got from Santa Monica only had a red led and that worked fine

I don't believe anyone is running a sump/fuge with red led lighting. I have however seen in the Santa Monica thread that there are quite a few guys using just Red LEDs for their scrubbers, also, when you go looking for plant leds, they seem to lean more heavily on the red spectrum.

Interesting. I'll look into the Santa Monica thread.
If only red LEDs can grow algae on a scrubber I don't see why it wouldn't grow macro algae.
Thanks guys!

They don't only use red leds to grow algae on the scrubbers. They've used all kinds of lighting for them.

Sorry RM, I meant if a fixture that only has red LEDs can be an option for a scrubber I don't see why it couldn't be used for macro growth too. I've seen people use all kinds of lighting from incandescent to halogens to LEDs on scrubbers :)
