I bought myself a cheap sodastream for fathers day recently. I did some research and lots of DIYers recommended getting your own CO2 tank and adapter hose to hook up to the sodastream directly instead of refilling the small canisters that sit inside.
I waited to make sure the sodastream was going to be something I liked before committing to the big tank. I’m a big dr pepper fan and the dr pete syrup wan’t very good. It was metalic and tasted like a cross between dr pepper and pepsi. I’m not a huge cola flavor fan. But I love carbonated waters and got the bubly natural flavors and those have been good.
Nobody in the family really liked their first drinks. A lot got poured out. But, I decided to pull the trigger and got a big 20lbs tank for no other reason than to save money on all the carbonated water I buy. I go through 1-2 cans per day. That shit’s only getting more and more expensive too. I took it to the local gas store and filled it with beverage grade CO2, ($40) hooked it up, and was pleasantly surprised.
Not just that it worked, but by how GOOD it tasted. Even plain with no flavors. Had others in the family taste to confirm and they all agree the new CO2 tank tastes WAY better. I wonder if the small canister that came with the sodastream was just sitting in a warehouse for so long it started to pick up a lot of taste from the metal or something.
Very happy, gonna need to retry the dr pete syrup, and see if that was the problem.


Check out BigClivedotcom’s YT channel, besides being an electronics geek he tries to carbonate every liquor known to man.
I just spent a little time this morning refilling canisters we use in our machine. I just have the tank with an adapter and I got a diptube put into one of my CO2 tanks to do that with, so it fills with liquid off the bottom of the tank. I put empty cyclnders in the freezer so they hold more when filling.
In your scenario, you just want the gas at the top for directly running the machine, but I don’t have room to put a full tank by the machine in the kitchen, besides being ugly.
