I have a 20lb co2 tank and a regulator that was built for indoor gardening.. got it from a friend. It has a cfm ball guage, i have added a bubble counter and diffuser.. it works but is very unstable. i see it wont hold accurate bubble counts. so i wondered what would the best way to cure this issue, i have seen micro needle valves, different regulators, and outright complete regulator sets, the cost for a replacement complete is 100. plus shipping, This one for example...Milwaukee MA957 CO2 Regulator Solenoid Bubble Counter | eBay
however i wondered about just upgrading mine to be accurate.. any suggestions as to the most economical and effiecent way to do that? or just buy a new one, which i hate to do because i feel like , hey i got one, just need to do something to fix it LOL...
