You still keep the benefits of trapping flocculated yeast per LeVassuer's article. I dont think the 3ft of extra tubing matters if you used the CO2 approved tubing, but remember the canisters have to push through all that line before you see anything in the bubble counter. If the tubing is the type that breaks down from CO2, I would think that very long tubing would mean the CO2 loss is high, but it might be years before you have to worry about this, and you could always replace it anyway. HTHI have about three feet of airline between teh generator and bubble counter so I Think this kind of defeats the purpose of having a place for chunks to get out, to relieve pressure, doesn't it. It's so I can take the little bottle down when I need to count the bubbles, or check the generator. Thoughts?
