Its taken 2 days, but ive read through 16 pages of this thread lol. Your tank is looking really good and I have learned alot, as I am setting up a 75 gallon also. Couple questions though....do you totally submerge your ehiem jager heater, or go just up to the water line? Also, have you not considered Vho's instead of t5's for supplemental lighting? I hear that they have better color/super actinics for the coral
