help co2 for a 4x4...!!! bubble counter-help !!!

hi all , i am in need of some expert opinion. i need the specs for a co2 system for a 4x4. the thing is my second guage on my regulator is broken so all i have to go off is the bubble counter. and i would like to know if anyone could let me know the approximate bubbles per second that my counter should be at. my tent also is running a 1000w with fresh air intake and vent outto the room the tents in. the fan goes off about every 10 to 20 mins. how should i set my co2 ? thanks for any response

It depends how big the bubbles are. Do this, get a gallon ziplock bag. Force all the air out of it. Put the bag over the spout and time how long it takes to fill it.

1 US gallon = 3785.41178 cubic centimeters

Its up to you to determine how many CC are in your chamber and what your PPM should be. Once you get that you can determine how long you have to have your valve open for.

you're a damn genius. thank you so much.
