Sorry for this questions but does anyone know this website http://www.marineandreef.com/shoppr..._aqualight.html, ?it has the 96 watt powerquad for 22 cheaper than foster and smith and has the sattelite 2x40 fixture for 93. I was wondering, does 16 watts make a diffrence? I want a lunar light to watch my corals at night and stuff but the tanks in my room, would it make a big diffrence, is it very bright(lunar light)? If anyon can tell me about hte website and if their reliable and about wattage and the lunar light, that would be great. My tank is 20 inches across, would the 2x40 watt sattelite fit, its 21" across. I want to keep some Zoos, rocordias, maybe a red open brain and some LPS. Is that possible and what would be the best option. The Sattelite has a fan so does it turn off when the lights turn off? If anyone knows about this please respond/comment, thanks.
