Anyone know of anyone who sells cheap like paintball co2 cartridges for my Fluval 20g Mini Co2 system?
Thanks!

I would check either amazon or ebay. Those would give you the best bang for your buck

The best way I found for "Cheap quality CO2" overtime is a 10 pounds cylinder. I was initially thinking about paintball CO2, but the cost of all was a bit lower than a 10 pounds cylinder in quebec... I have to refill it each years.

All the ones on eBay are unthreaded. Can u give me a link to some?
