I came home today and checked on my carbonating beer, not that i can do much but just stare and smile. I noticed that the high pressure gauge is much lower than it was yesterday, i sprayed all my gas connections with starsan and i see no bubbles what could be going on here?
Co2 tank way lower today but i cant seem to find the leak

The regulator is not a good measure of whether you're losing gas or not. You really need to weigh the tank to tell. A 5lb tank weighs 7.5lbs when empty.

Check the weight of the tank compared to the tare/empty weight. When you leave your co2 tank in the fridge the high pressure gauge drops.

Where is your tank located? Large temperature changes can cause the gauge to read differently.

How many kegs have you gone through? The gauge moves very little over the course of a few kegs and then drops like a rock when its empty/near empty
The tank is in my kegerator right behind my keg sitting at 40f
This is my first ever keg. I did notice that the needle has gone up again so im a little confused at this point l.

Ya, will notice a significant drop in pressure if you went from ambient temp to serving temp.... Is that the case or did it happen in the kegerator?
My keg and and co2 were chilled before kegging and yes it happened in the kegerator.

Based on my own observations, a filled tank will usually read around ~750 PSI if not refrigerated. Once refrigerated, the pressure will drop to and maintain ~500 PSI until all the liquid CO2 is gone, then it will drop very rapidly to zero. What does your tank pressure read now?
Ill have to check when i get home this afternoon but ill let you know
Sorry for the delay but the gauge is sitting right under the 40 mark.
Not at all true. The Tare Weight (TW) is stamped on EVERY tank.
Did the OP chill the tank? It's normal to see the pressure in the tank drop to about 500 psi when in the fridge. It'll stay there until right before its empty.
The place where i dropped off the tank chilled it down to freezing temps before they filled it for me.
What PSI is the HP gauge reading now? What temp is the tank being stored at?
Its sitting right under the 40 mark on the guage and its in my kegerator at 40 F
40 bar I assume (not psi)? Then your tank is somewhere between 5-95% full.
Mass is the only way to know 100% though.
Yeah right below the 40 bar on the hpg. Ill just have to weigh it out like you folks have mentioned. But ar this point it's been holding steady so i would say im leak free. Thank you everyone for the help.
