Thanks for the welcome Texreefer.

Hobogato, the tank is not drilled or reef ready, just a 265 gal perfecto glass aquarium. My existing wet/dry system does about 1800 gph and before I moved it had been running since 99 without problems. I believe the overflow box would only be able to siphon out maybe about 50 gallons or so if something were to go wrong and a hose were to come disconected.

I am mostly interested in the new wet/dry system because of the extra large sump, which should allow me to put a protein skimmer in it and allow me to put extra water in the sump for vacations and such to handle evaporation.
