Matt,
Without my chiller my water temp is at 88. With the chiller my temp is 82 to 83 after all the lights come on. I actually need a bigger chiller so I can put more lights on the tank. And I am adding a second SCWD (close loop) and then I can remove (many) powerheads from my tank. Here is what I have been thinking about my lighting. 12 400 watt MHs, 6 20,000k XMs and 6 10,000k Ushios. = = =center brace ===. Ushios in the rear and XMs up front? Then removed all the pcs I use for supplementation. What do you think?
Jim
