15 watts per gallon wouldn't be too much? I'd think that would burn up any mushrooms you have unless they are ricordea and the tank is shallow so placing on the bottom wouldnt help that much imo
. They do make 70 watt MH
's. Wow I just looked at the price difference between a 70 watt and 150 watt SunPod HQI and its only $20.
Those Dual Satellites are 20'', 2x40watt compact flourescents. That would be 8 watts per gallon- $125
Coralife has 20'' 96 watt Quad Tube Aqualight- $120
JIMO I would go with the Coralife 96 watt fixture cause I would be afraid to burn up mushrooms (which may still happen) with the MH
and the coralife is $160 cheaper, which you could spend on lr
and livestock. All the fixtures I have are Coralife and I love them, I have a 65 watt over my 52 gallon FW
, a 32watt over my 10 gallon nano-reef since low (mushrooms) light might get t-5's later, and 130 watt over my 20 gallon nano-reef. I've never had any problems with Coralife. All the prices I quoted were from the newest DrsFosterSmith.com catalog.
