  1. Lighting
    I just picked up a 55gallon long tank. The specifications are 48 1/4 "long x 12 3/4" deep x 21" high. So, guessing I won't need 110 watts of light on the entire tank to grow UG, rotala, or HC. Not sure though. I may have to get 2 smaller lights and put them next to each other on this tank...
