I'd like to quickly go over my second experience with a saltwater tank and where it stands right now. I lost my first tank to Hurrican Isabell a couple of years ago while in our rental house - we were out of electricity for a full week and when the power came back on it was obviously too late...

the last time my system was running (before we moved to the new house I have a FOWLR which I was not very happy with. The nitrates went through the roof unless I did 10% water changes weekly. So Ifigure this time I'll set up a sump system with a DSP in both the main tank and the SUMP (with...

I finally have my carpet in my basement and I'm almost ready to turn the tank back on. It's been off for two years. I got 275W of VHO and want to go reef in my 55. How close to the tank do the light have to be to get down to the bottom with enough wattage to support corals/clams? thanks!
