Whatever the total bubble count into your tank is, that is how much CO2 you
are putting in. Of course, bubble count is meaningless alone: you will be
referencing it to actual CO2 content of the tank water. Once you know about
how many bubbles you need to achieve a given CO2 level for your system
(e.g., pH/KH ratio), you can keep an eye on things without having to measure
everything all the time.

Personally I would just simplify and have only one bubble counter feeding
into one cannister. Otherwise you'll need two metering valves to control CO2
rate, more plumbing to split things up pre-metering valve, etc. I suppose
you could split the CO2 line after a single bubble counter and send one
outlet to each of the 2 canister filter inlets if you wanted, but I wouldn't
think that would be necessary.

Have fun.
