I'm finally going to order a kit from rapid for my 65 gallon. Here's what I have planned for the build, maybe some experience people can offer a little additional advice. Anywho, here's the details: Tank Dimensions - 36L x 18W x 24H Goals - Softies/LPS dominant tank, (MAYBE one or 2 SPS up towards the top) Heat sink - 8.460" x 30" from heatsinkusa Leds - 36 Dimmable kit from rapid with Arduino PWM controller 12 Royal Blue 6 Blue 12 Cool White 6 Neutral White I do not want to hang the light any higher than 12 inches above the tank, so I do not know exactly which optics to go with. Does anyone recommend optic choices? Any other opinions?
