Co2 Injection - How Long Does The Tank Last

[killudead]

I have a 10LB tank that i basically have to refill every 17 days. Maybe I need a different needle valve. I have the JBJ solenoid with needle valve.

to my knowledge, i have the bubble counter set to 3 bpm in a 75g heavily planted tank.
I keep an eye on my co2 indicator and all looks well.

I need some help here pls.

I used disposible wielding bottles as well. Mine lasted about a month-2months if I remeber correctly (not had my planted tank for awhile now).

Sounds like it is using too much. I would also strongly recommend using a CO2 indicator to make sure your not overdosing.
