Great point, Tyler, about making sure the water is cold. The colder the liquid, the more carbonation it can support. In technical terms, you want to get as close to 5 degrees C as you can (water does a weird thing at 4 degree C when it actually expands before going back to contracting as you cool it further so most commercial devices won’t cool below 5 to avoid dealing with the fluctuating volume). Sodastream can absolutely push more CO2 into your water than sodamakers provided your water is cold. I have tested this myself.

I’m wondering why they want it back if its of no use to them. or is it….

you aren’t using ice cold water when carbonating. i also make sure the Co2 is injecting into the water, don’t leave a gap as suggested by someone. i press the carbonate button all the way down until i get the bzzzz sound. I completely release the button. I do that 2 more times and it’s as carbonated as you’d want. For the record your soda stream can carbonate it more than the soda from the store. But you have to start with very cold water.

Another tip, I use Crystal light powder and mix 1 packet with 1/4 C water to make a concentrated syrup. This will make 2 liters of soda. so re-use a 2L soda bottle to hold the finished product or use 1/2 pack of crystal light if you have a digital scale. I think each pack is 9 grams or something obnoxious like that so it would be 5g crystal light mixed with 2 TBSP water per SS bottle. Verify this first. Favorite flavors are Fruit Punch, Grape, and Orange. Lemonade aint too shabby but use yellow, not pink. And it’s all 0 sugar!

final two cents: yes, flavors are sometimes hit or miss. Least favorites that are what I really would like to see: Root beer, cream soda. Best flavors, Dr. Pepper knockoff (can’t remember the name), Starry, Pepsi (I prefer coke but it’s not available.)

Ah yeah, don’t go to the paintball place for CO2 there are oils and things that you dont want

I’m rolling on the floor reading your comment. Thank you

perfect scenario thanks I’ve been doing it for years

The canister is labeled at 14.5 oz. Place empty cannister on a postage scale, zero it out, add dry ice till you reach 14.5 oz. attach valve and done. I buy dry ice pellets, easier yet.

In Canada, go to Save On Foods and the empty cylinder are $16 returned with the original cylinders are purchased for $34.

can I get the information of how he calculated the weight for the volumn / pressure of the cannister?
