As I posted over in the first-world problems thread, the local store that had a reliable supply of Sodastream CO2 cylinders now only carries the newer pink ones, which are incompatible with the classic blue ones I need. My wife drinks lots of seltzer, so I’m trying to figure out the best alternative:
- Buy a new Sodastream that takes these cylinders.
- Keep the existing Sodastream and adapt it to use paintball cylinders.
- Keep the existing Sodastream and adapt it to use a larger CO2 tank
- Keep the existing Sodastream and set up a rig to refill the cylinders from a big CO2 tank.
- Buy a Spärkel system, which uses citric acid and baking soda to make CO2.
(For those unfamiliar with the process, here’s a site that explains several of the options.)
There are pros and cons to each, and it’s been a pain to try to balance out the expense vs. convenience aspects of all the different permutations.
I’m particularly interested in hearing from Spärkel users about their experiences with it, especially if you’ve used non-Spärkel carbonation powders. The possibility of saving a lot of money by using bulk citric acid and baking soda is a major draw to the system, but the company advises against it, says their powders are specially made, and that using others could damage the machine and void the warranty.
If that’s all (or mostly) BS, I’m very interested in considering Spärkel, because it means I can order the powders online and don’t have to run all over creation to find CO2.
Any advice, suggestions, experience to share? Thanks.
