I've been running with a filterguys canister with media cartridge (about 1/6th of a gallon which is a little over 2 1/2 cups) seems to last about 3 weeks for me. I really should start keeping notes, I used to and stopped for no good reason other than laziness.
I can tell when the cartridge is running low by the PH. I usually replace when there is still a little bit of white left.
either of these stores in rochester should be able to get you bulk media. If you work for a company you might be able to get a discount on top of the already nice pricing
this falls under medical, so you might want to call the medical branch
