I have a 55 gallon, and I won't be able to upgrade to a bigger tank for a year or two at least. I like the combo light by Outer orbit, 48 inch 2x150 watt mh and 4 t5 actinics, with moonlights. Will this be enough light for this tank and possibly a bigger one (120 or so) or should I buy 250's instead? Please tell me what you think. No one in Sacramento seems to be able to help! Thanks
