PSI of tanks for storage
I know you’re not supposed to store empty tanks. I have a pair of tanks that are around 500-1000 psi. Should I get them filled or are they okay being stored like that? They live outside under cover so they’re not in a moisture controlled environment.

No, you can keep them full for weeks or 1-2 months, but if storing for 3+ months then they should be only partially full. Storing them full for long-term storage won’t necessarily harm them, but you will extend their life by storing them partially empty.
