Update looks great! Good job on the black pvc... it looks so much better then the white. I love how you made it directional
Those turbos are doing a great job! hehe.
Sorry to hear about the temps still being hi. 82 is kinda high I guess, though I have been keeping my tank at 81 constantly at night to keep the water warm due to my black ich problem. With the halides on it creeps up to just under 84 after 10 hours of MH.. but I keep the room in the mid 70's. When my A/C broke my tank temps went up to 84 without any lights on at all... so there def isn't much room for error with your current setup!
I don't know if this would help at all... but have you thought about getting a couple of Tunze's powerheads? You could always use them instead of the closed loop for current? Could even hook up the wavemaker stuff to it... but at that point the chiller would probably be cheaper! Idk.. just throwing thoughts out there....
