how long would a 20oz co2 canister last for a 55g? estimate lol
tbh i cant seem to find places around my area to fill the larger canisters, or to even sell those. ebay is an option but then again im on a budget...
if the 20 oz canister will give me a couple of weeks or a month i can easily refill it and have a spare on hand, those larger ones im just not familiar with buying/refilling
