Hello,

I have a 500g JBL CO2 bottle which I currently refill by taking it to the fish shop and having it replaced for a filled bottled for £9.

I was trying to look for other cheaper alternatives and made some phone calls, but it seems that gas suppliers would only do that if you rent the bottle from them and pay a monthly fee, which wouldn't be cheaper.

Anyone knows of a cheaper way to have CO2 bottles refilled?

Any information would be appreciated.
Thanks in advance.
