2. I've killed a few corals but bleaching has never been the case.

are they for the shimmer effect?

heat sink design - I'm designing a 16" x 60" LED fixture for a 24" x 72" (x 17") tank. Initially I looked at the solid heat sinks but the weight& price were prohibitive, plus the heat sink is mounted horizontally which isn't ideal for convection flow. So, I'm going with 5 aluminum channels (1.5 x 1.75") on 3.5 centers with cross straps (physical & thermal use) as well as aluminum vanes to enhance convection flow. [The vanes will also behave as light shields to avoid viewers looking at the leds]There are 6, 3" diameter fans (3/side) to blow air across the fixture. The LED's are on 5" centers with a 50% mix of white & blue. The fixture is in a wooden enclosure with slots along the horizonal panel for heated air exhaust. I'll also use optics to control the light beams. Jim

I also need to add pictures of my 30G tanks with the LEDs on them.

qfrisco; On your turned off system use an ohm meter to hunt down your problem. Measure from a bare un-anodized place on the heat sink to the power pads of the star to see where your problem is. Then you can properly address the issue.
