you may have been just running your co2 a bit high, you have a needle valve right?
You most likely had a leak between the tank and the connection to your regulator. Did you use a washer (nylon) or a perma-seal? If you did, next time put a bit of soapy water around the connection to see if any bubbles form. At the rate you mentioned I would think it would last for at least 6 months minimum.
When you remove the regulator from the CO2 tank, you must replace the nylon washer every time, even if it's just been replaced. Those nylon washers deform with use and are strictly a one use and throw away item.... I did have a nylon washer but didn't replace it when I had to disconnect/reconnect the reg when I replaced the solenoid since it wasn't that old. ...
It's ok, you can call me stupid for this one! I screwed that one up. Sad thing is I questioned the need to replace and went against my gut feeling and told myself it'll be fine since it had only been 2 weeks at most. Again, live and learn.I think this is one of the requirements in the learning curve for any folks? Sorry, but I would guess that you have been caught in a very common trap and left a leak.
The reason for the high pressure not moving for a long time is one thing that leads people to miss leaks. They think of the gauge as showing things are fine if they are not aware that the gauge doesn't work like a car's gas gauge. This gauge shows there is still the same pressure even when we are really using the liquid portion out of the tank. the gauge doesn't start down until after all the liquid portion has gassed off and then the pressure begins to move down. But that is only the last small bit of CO2 and the rest is likely wasted!
One point that I learned is that a big leak is as easy to miss as a slow leak. Very odd but easy to do. When mixing a bubble /soap solution, it is important to mix it really super thick. Think like shaving crème or whipped cream. I do this by using a lot of liquid soap and a little water and then "whipping" the mix with a small hobby brush.
Reason this is important is the way gas can blow things off or take a short time to blow a bubble big enough to spot. You need the soap thick enough to cling to everything, so that you can either spot a big leak as a bare spot or a small leak after a half minute or so as it blows a bubble.
This is a case of taking time to go slow can save a whole bunch of time. It may take 15 minutes to do a good check. But thinking how long it takes to disconnect, take the tank there and back and then reconnect and it can be almost a no-brainer which saves the most!
Not to mention the repeated kicking tends to wear the seat out of your pants?
Been there, done that and learned the hard way!
Interesting... especially considering I forgot to ask for a new nylon washer. Good thing I have an extra. Might have to look into buying one of these. My tank does have the threads so it is compatible.When you remove the regulator from the CO2 tank, you must replace the nylon washer every time, even if it's just been replaced.

Next time just get one of these. Just remember to grab it when you swap the tank and they don't keep it. CO2 Tank Leak Stopper https://www.amazon.com/dp/B0064OFAQU/ref=cm_sw_r_cp_api_Nny8yb5JHD2SN
Co2 Regulator Washer (nylon) | BeverageFactory.comHighlights
Reusable nylon plastic washer
Has grip edge to help keep washer in nut
Goes between the regulator and the Co2 tank
Please Note: May be red or white
AFAICT not necessary and self defeating as one has tested the hp side..Unscrew from CO2 tank and watch the low pressure gauge.
And what happens when the leak is at the top of the bubble counter?There are other ways to do a leak check, and soapy bubbles may miss leaks.
Connect the Reg to CO2 tank. Turn the knob to working pressure of 0. Turn on the gas and shut it off. Check back in an hour or 2. High pressure should stay put. This means you installed the reg on your tank properly. I do this every time I get a tank refilled.
Next check the rest of the reg... make sure solenoid is off. Release some pressure into working pressure (low pressure gauge) to its highest setting or close to it. Then turn the knob closed on reg. Unscrew from CO2 tank and watch the low pressure gauge. If it drops the you have a leak somewhere between the 2nd stage chamber and your solenoid.
Recently I had a leak at my solenoid. Took me a while to figure it out, I had to redo all connections, tested the regulator separately by plugging the outlet until I was able to isolate the leak at solenoid.

Since I already have things going and I don't have any more washers (forgot to get some last night and the two places I know I can find them are closed for Easter today) so going to do this test next refill. Hopefully that is many many months from now.I do not replace the washer each time. I do have a small stack of them on the shelf but there is also another point to keep in mind. As we do this, we will get the "feel" of how much torque it takes and part of that is what wrench we are using. This is a good sturdy fitting that can take the torque most of us can put on the wrench so get a good one. If we use a short little wrench, we are more prone to leaving a leak. So I recommend spending a few bucks like $8-10 to get a really good 10 inch "Crescent" type adjustable wrench. It may seem like a waste to have a wrench if all you use it for is the CO2 tank but then you have to balance that against either replacing the washer each time or potentially leaving a leak.
And if you had the wrench, there might be all kinds of things you could use it to fix!
