I've decided to get back into darts! I bought a 135 gallon tank from a friend of mine that came with 5 green legged Bicolor's. I wanna redo the whole tank. The tank used to be for saltwater and they kept all the lighting for it. The tank holds 6 58inch 80 watt t5HO's. I would like to change them over the 6700k's as right now it has half 10k and half actinic. My problem is I can't find these bulbs anywhere! I've searched all over the net and keep coming up empty handed.
