DuffyGeos March 26, 2015 Share March 26, 2015 I was curious what height people keep their T5 lights over the water surface. How are yours set up? I know this will depend on: -How many bulbs? (1-8) -What are you keeping? SPS, LPS, Mixed? -Depth of the tank? 10"- 36"+ -Any other lights? LED, MH, VHO? I have seen everything from 4" to 36".......

Origami March 26, 2015 Share March 26, 2015 When I ran T5's (a few years back), they were set in a canopy about 10" off the surface of a 180 gallon tank. With the deep sand bed in place, the distance from the water surface to the sand was about 19 inches. I ran seven 80 Watt (60") T5HO's plus one 140W Super Actinic T12 VHO in the arrangement. The arrangement had decent-quality reflectors, but I can't remember now what brand they were. I was keeping SPS mostly, but a few LPS were in the tank, too. No other lights, except for a few LED moonlights which added virtually no PAR. Link to comment Share on other sites More sharing options...

DCReefer1964 March 26, 2015 Share March 26, 2015 The answer is PAR reading is what will determine distance from the surface of the water. Link to comment Share on other sites More sharing options...
