how long did ur CO2 tank last?
also how big is ur fish tank and how many BPS were u using?
I'm asking cuz i increased my BPS from 2bps to 5bps for 2 weeks when i replanted my tank and noticed the gauge read from 900psi down to
-900psi in two weeks (ur answers will give me a rough idea on how long b4 i refill my co2) gauge is steady ATM

tank specs
volume:30g
BPS: (current) 2BPS
CO2 tank size:10 lbs
duration of use:3 months

TIA

I use 20# tanks. One tank on a 55gal at 3 bps lasted all most two years and I think I had a small leak in the bubble counter. I have another 20# tank that I am running 3 tanks on. Two tanks at 3bps and one at 5bps. This tank is over eight months and is still at 900psi. I get refills when my tanks reach 600psi. Depending on if your CO2 system is a low or high pressure system you can go lower without worrying about a CO2 dump.
