i was wondering if some of you might think that a single 1000watt mogul bulb (w/ Lumenarc) is too much for a 90g. My current plan is to go with just a 400watt.
Just the usual SPS and clams. It'll be a cube, so I'd like to go with a single bulb. I was going to go with a 400watt 10K, but through 'what if' I went with a 1000watt 20K.
