I am torn between the 2. I have a RedSea Max 250 with ATI Bulbs and a 90 Gallon with (2) 150W MH. I get better growth with the T5's and keep SPS in it with no problems. I can get a used 20" Current Nova Extreme 6 Bulb or a 24" 150W Sunpod. Both will cost me the same price. I am concerned with finding the bulbs for the Nova Extreme. I hear that you are limited in the Bulbs. Hard to find 460nm and I am not a fan of the 420nm. The 90 got up to 82 degrees with a canopy on it. I put a fan in the canopy and the temp went down to 80. This one will be a wide open tank, so don't think the Temp will be bad. Not a fan of all LED on the tank. Like them for Supplement
