I certainly don't see my current bell set-up doing much if
I add a second DIY bottle of CO2! Thanks,

Try 1 gallon juice bottles. Make you health ;-) and the cat can't tip
them over as easily. The bigger allow installing brass bayonet fittings.
Much better seal. I get them with an O-ring and brass nut for a couple of
dallors a set at a plumbing supply store. I run three 1-gallon jugs per 55
gallon tank.
