Yes, the regulator and selenoid is included. Sorry, I forgot to mention that.
BTW, I work for New Century Mortgage, and do not expect to have a job next week. I live in Fontana. That means that if I'm no longer working in Irvine and you live in OC, you'll have to drive to Fontana to pick it up.
The rest of the tank will be for sale soon too. That includes 3 x 250W MH with VHO lighting, a 41" Beckett Skimmer, about 200lbs of live rock, 100 lbs of dry base rock, all live sand (you may not want the rock and sand, I have bad cyano issues right now), three pumps, and two RO/DI units.
