Losing pressure in paintball co2 fr aquarium.
Hello, I'm new to the website so I'm not sure if this is the place to ask this kind of question about an urgent DIY co2 problem so sorry in advance.
I am using a 24oz diy paintball tank along with a Aqua lab regulator which includes a solenoid, needle value, pressure gauge, and CGA 320 paintball adapter to inject co2 in my 20 gallon long tank at 1 bubble a second. I recently made the switch from DIY co2 citric acid and baking soda setup so I don't have much experience with pressurized co2.
The problem I've been having for a couple of days is that I keep losing pressure in the tank. First day I used it, it was reading 1000 psi, co2 was coming out, everything was great. Next day, it dropped to 600 psi. The third day it dropped to zero, no co2 was coming out.
I didn't hear the any leaking (if that's a good way to find the problem) so yesterday I took the tank back to a clerk at dick's sporting goods where I had the tank filled. He said that the tank was fine and that I only lost 4oz of co2.
I brought the tank home refilled, plugged it back in, 1000 psi again. Co2 coming out again, great.
In the morning it was still reading 1000 psi, in the very late afternoon, the psi was almost down to 0 with barely any co2 coming out.
So I'm trying to firgure out why I keep losing pressure. Could there be a leakage in the regulator? (if so I wouldn't know where to start looking) regulator is broken somewhere? Any help would be nice.
