Hello, I am looking to upgrade my lighting system to one of your led retro kits but have been unable to find answer to a couple of my questions. My tank is a standard 150 gallon, 72x18x24. My lighting is 4 PC bulbs, 2 are actinic blues and to are white 12K bulbs at 96 watts each, and I have one green ricordea. My questions are: 1. How many leds will I need for doing Ricordeas, zoanthids and some anemones? Mainly just softies and anemones. 2. The lights will only be about 11-12inches above the tank so what Par lens should I use? 3. Does it matter what type of Aluminum channel I use? 4. I plan on making them dimmiable so do I need a Potentiomiter for each driver or just one for the all the whites and blues? I think I only need to two but figured I throw that out there since I'm already asking some questions. 5. What level should I start at so that I don't kill the ricordea I already have? Thanks in advance!
