This is my first post but Ive been trolling for days. Great info all around I cant get enough of it. My question is I'm in the process of building a tank for an octopus 55 gal. My question is lighting? Im going to build my own led light. I'm in the process of picking out the colors of the leds and I just wanted to run it past people that know what there doing to make sure im on the same page. It was going to be about 36 leds or so. This is just a ruff setup. I was thinking about 18 royal blue leds. And about 9 white leds. All set at a pretty dim intensity. Then make up the other 9 with a red led for nighttime use. I just want to make sure that its enough but not to much . Thanks for all the help and Im looking foward to getting this rocking and rollin'
