So I decided to jump headfirst into building an ATS... we will see. I have a 90g reef tank, after doing some reading I "planned" 4x6in screen, 4 SemiLED DEEP RED (wired series) 2 SemiLED Royal Blue (wired parallel then series with red) Steves LED Driver (single) still working out the heatsink... rather not go with MAKERS. Meanwell LPC-35-700. My original idea was to create my acrylic ATS to be lit from one side and later down the road if I upgrade my tank or need more scrubbing power I would just add another LED fixture to the other side. What do you guys think? any further suggestions...?
