Hi Nick, my name is Sergio I work with your brother Ken. I was looking at some of the pictures from your tank, man what a beautiful tank. I have a 72 gallon bow front that I've had for a couple of years. I have not had too much luck in keeping corals, my nitrates and phosphate are always on the high side. I have a wet/dry filter that I think is what is causing that problem. I would love to talk to you to see if I can get some tips.
