how do I know when water bottle is fully saturated, when carbonating with a CO2 tank and regulator?
Where do you get your RO water?[...] with a 2 liter soda bottle filled with boiled,cooled , then very chilled (34º) Reverse Osmosis H2O [...]
That's not an easy way for doing at home. Even in a lab that method would be a challenge.The proof of the "full" saturation could additionally be 'proven' by weighing the bottle and finding that it was heavier than pre-injection weight by, say, 4 grams per liter. were I to go to that length.
Thanx for comment. We have a R/O system for our drinking water, well and good. I'm bringing it just to boiling point first, in order to release the already absorbed gases (air, hydrogen??, etc) that are in the water naturally to begin with. The release of those gases then allows for greater/more complete subsequent saturation of the CO2. I've definitely noticed a greater amount of infused CO2 after doing so.Where do you get your RO water?
And why are you boiling and then cooling it? RO water should be perfectly potable without doing that. You can carbonate it as is, while it's cooling to 32-34°C.

Carbonation levels depend on the temp of the liquid (water) and pressure of the gas, when it has stabilized (no more CO2 being absorbed). There are tables for that.
Thanx for your comment as well. I have one of those and have just started using it in my 'new' carbonating system with the regulator. I chill the bottle as cold as possible, down to the 32º-34º range. I've been advised to use pressures in the 35-50 psi range while carbonating. I just don't know when to stop the actual carbonating process, and shut off the gas flow. What is the signal that it is done?????? Cheers, and happy M Day.The best way I've found to carbonate a 2 l PET bottle is a ball lock screw top plastic cap. I chill the bottle and pressurize it to 20 psi. Of course the pressure drops as the CO2 dissolves, but you can hit it with more pressure at any time. They cost about $3 each on Amazon.
