so i was having problems with the lights heating the water to about 84F
so i installed 2 large computer fans to the back of the canopy and have decreased the temp to 80F while the halides are on.
i will be adding fans to the stand too and hopefully it'll bring the temp down a couple more degrees.
i also re plumbed the return to the opposite side of the overflow as i was finding that i had film forming on my water.
