George, Fantastic build thread. I couldn't help but notice the LifeReef CaRx. I LOVE mine. I have had 5 reacotrs over the years and Jeff's is by far the best I have owned. I noticed you are using a uniweld regulator. I have been thru my share of regulators as well. When it comes time to replace that dinosaur, get a Milwaukee MA957. it was well priced and has the most precise eedle valve i have ever used. and it is built like a tank. I've had M3's, uniwelds, knop engineering.... the Milwaukee is the best so far....
HTH
