Many people on the internet were questioning weather or not the Fluval CO2 20 System has propriatery threading on their 18g cartridges. Seeing as a package of 3 Fluval brand cartridges costs around $25 I thought I would try a "non-fluval" threaded CO2 canister. I went to my local bike shop and picked up two 16g threaded cartridges for CO2 bike pumps for $8 and they fit perfectly! But 4$ a canister is still kind of steep in my opinion but here are some alternatives that will work:
Canada: Mountian Equimtment Co-op sells 20 for $28! (I tested these as well and they are only $1.40 each!)
USA: eBay
I scoured the internet trying to find a concrete answer and found nothing so I am just posting incase anyone else was wondering!
Cheers
