Time for a new regulator?
So I bought my regulator probably a year and half ago for like $40 used. It's a JBJ. But at this point, even when the solenoid is off at night, quite a lot of CO2 is going through the diffuser. I've heard of solenoids wearing out eventually but I'm not sure if there's maybe just an easy fix to this. It's not causing a problem right now, all the fish are still doing fine, but it's wasting CO2 and I don't want to wake up one day to see that all the fish got gassed. I am more than willing to replace it but I just wanted a couple of opinions first.
