I'm considering starting another planted tank using a standard 120 (4x2x2) and I was wondering if I could get by with T-8 or T-12 lights. The tank will be primarily crypts with some anubias and java ferns. I know T-5's have better penetration because that is what I'm using on my reef but the bulbs are so much more expensive and I wouldn't mind if this tank was a little cheaper to run.
