how long can co2 5L last with 5bps for 8 hours everyday ?
how about 3 bps or 4bps ?

my 2L, 2 bps, with solenoid for 7hours daily... drop checker show green...lasted for 5-6 months... tank pressure was 1100 initially...

[sawzai]

nice. how many gallon is your aquarium tank ?

5bps should last around a year or so, or even more, depends on how full your tank was top upped to.
3bps and 4bps, just do the maths.

Bps may not be a good indicator of your co2 concentration too. Depends a lot on how you inject to pressurised co2 into your tank also.

Bps is not accurate to gauge co2 dissolved in water. You need a drop checker.

my tank is 2feet ..estimate around 70litres
