It may have been closer to 800...I just know it was close to 1000. It's at 400 now and it's only been a couple weeks. I need to get a bubble counter maybe to make sure I don't have the CO2 turned up too much even though the fish seem fine. I thought that a 5# tank should last several months...not weeks.

It's a DIY Rex Grigg style reactor.

I'll check again. I'll check everything from the tank to the reg. to the line to the reactor. The tank is steel...I'll weight it next time before taking it to the shop for a re-fill and again when I get home. I don't think I am being shorted...the place I go to is a very reputable welding shop...but then again, you never know.

Well...I guess I'm a dumbass...it was leaking at the connection between the tank and the reg. Some teflon tape took care of it. I checked it there last time when I first got the tank...maybe I had it threaded just tight enough then that it didn't leak right away though the CO2 only lasted a few weeks like this time. Guess a lesson learned. I still wanted to find out what the pressure was supposed to be on a full tank...for some reason I thought it would be higher. Guess I am just use to SCUBA and SCBA tank that have pressures of 3000 and 4500psi.

Oh yeah...and thanks a bunch to everyone that chimed in.

It has a nylon washer and it's torqued enough that the washer is imprinted from the reg. I don't know. The leaked did stop though. I really cranked down this time too so maybe it's just from being tighter, maybe from the tape, maybe from both...I don't know...it's not leaking now so that's good enough for me. I'll definitely get more new washers next refill...this one is reused from last time. This tank can't use a permaseal, I'm hoping my 10# tank can...I never looked. I am waiting for them to hydrotest it. Should be done soon I hope. There was like a 4 week back log on testing. That's why I have the 5# loaner.
