Time for a new Immunity Challenge. I think Dave's consumption numbers are a 
little (well, maybe A LOT) low, at least compared to my consumption with trickle 
filters. Tell me about your CO2 consumption for pressurized bottles (I don't 
care about yeast CO2 consumption). Pertinent data should include:

Tank size
Target KH 
Target CO2 level
Reactor type
Filtration (trickle, biowheel, canister, ...)
CO2 off at night?
Subjective plant growth (OK, less than I want, way to fast, ...)
How long your x# bottle lasts

Send your data to <booth at frii_com> (DO NOT reply to the address this is being 
sent from). I'll collate and report when the deluge becomes a trickle.
