Ok on my 2G tank I have a Compact Fluorescent Dual Reef 50/50 Lamp - 14,000K Actinic & 7,400K Daylight but I noticed today that my Zoos are reaching for light. I was thinking of just getting another bulb for the fixture that I already have. Possible??? If not I geuss that Im going to need to get a better light. Problem is $$.
