Refill popular Sodastream Bottles of 450g (most common) - 600g of CO2 - this is similar to Sodastream Refill. This tank can carbonate and dispense about 60L of carbonated water. Similar brands of cylinders are marketed as 60L cylinders for this reason. Don't waste money on expensive home deliveries and swaps at the supermarket duopoly. 
 
We are located in Sydney, North Rocks next to Parramatta. We can swap the unit or fill a unit you already have. It takes less than 5 minutes to complete the transaction depending on any waiting customers and the number of bottles. With larger orders, we can prepare a swap and drop, order.  
 
We use food-grade CO2 to fill the unit from a reputable gas supplier - BOC. 
 
Attention Craft Beer users: If you are only using Soda Refill to dispense beer not carbonate water then you will get about 100L.
