LED Upgrade

again, while im not evil, I would suggest against 40 deg optics on that type of setup.. you're going to end up with quite a bit of spotlighting even if you space them pretty wide, you will need to place the fixture over 18" above the tank to get good color blending.

Yeah, sorry, its been a while since we talked about this. I couldn't remember all the details. Thanks

I agree with XSiVE about the optics. 40 is too tight. If you needed them at all, 60 would be as tight as I'd go. If you are doing a mixed tank, you could get away without using optics at all.

As for the number of LEDs you would need, at a minimum 36, in a 12x3 array. Meanwell ELN "D" drivers are about as easy as it gets with the least amount of parts. To get more of a Fiji Purple look, you would have to use warmer white LEDs. I advise against red LEDs as they can be extremely distracting.
