ah, I guess I missed his change over from the eBay LEDs he was running. Still, his tank has had LEDs over it for a while now.

They definitely grow corals here are a couple shots of my tank on a diy led fixture

July



November


The growth has been good, I will be switching over to mh/t5 just after Christmas. I feel like I'm lacking some color that the Diy leds aren't able to provide.

What specific colours LED's have you got on your fixture? How many?

I built it about a year ago with 72 3w Cree RB, 24 cw, and 24 high noons. It's a little late to add some of the new LEDs that have came out unless I want to redo it all.

CW flushes out a lot of green and blues. Red looks better but thats all for CW. That's why people started using nutral white (4500k-6000k). 2:1 RB:NW gives 14K look, something for which people moves to MH I guess.

For full spectrum, it should be 5:2:2:1 RB:NW:TV:RGB for full spectrum. True violet (405nm) actually pops up a lot of colors that RB:NW cannot and it triggers a specific region of photosynthesis too. UV (390nm) on the other hand, is actually bad, possibly because the wavelength gets shorter in water from the source.

I am running 3 Sols with some DIYs. The Ebay fixtures were too loud for my liking even though my corals still grew. I've been on LEDs now for a year and 8 months and corals are still growing. Over the last year I've removed at least 15 colonies of sps (most had to be broken in order to fit in a 5 gal pail). So in a nutshell, yes, LEDs can grow sps just fine and the colours are still beautiful.

Hasn't been a more informative thread than this one in a long time. But yea good idea. But don't shut the Random Thought Thread down. It's really helpful to the hobby.
