tank is 72x30x2 hey everyone my ? is should i go with 400mh or 250? i was thinking 400 because since the mh has to be about 14 inches from the bulb to the water plus the 30 inches high on the tank your talking about 44 inches to the bottom of tank, i just feel that getting 400 mh 12k at 3x times would do it, and get a coralvue ballast where if it was to much i can dim it down what do you guys think??
