Well, I don't know how to quote more than one so here goes.thedudefrom1976;3915111; said:I have one 2L bottle empty with some gravel in it as an overflow for any waste that might come out, but frankly I dont need it, it seems.

I ask because im inspired by your setup to make that empty bottle a co2 producer as well
