Thanx Nissan and Subbielover. I'm in the process of constructing a conduit to hide all the wiring. The lighting is not MH. It's a Current 20" T5 6x18w. I was running the original hood and had modded it from nanotuners, but I had a serious heat issue so I decided to go topless and glad I did. Tank stays around 77.6-78.4 degrees. Hey Nissan! What's this 24,12,8 deal you asked me to join?
