it seems that even when hooked up to the faucet via the python assembly, the chamber doesn't not fill up completely. it has to be turned completely upside down to let all the air bubbles out....
[edit]
i figured out what was causing the excess bubbles, resolved it, and did another test. with the proper flow rate, the system works great. some of the tests i did involved squeezing the co2 generator and creating a large burst of bubbles. it takes about 15 seconds for the bubbles to go from this size [--> o ] to impercieveable. all i need now is the rio 600 and a small check valve!
