1. Carbonate fresh cold water only! Temperature of 4-8°C is best, so try using water straight from the fridge.
2. Keep your bottles away from excessive heat & direct sunlight. Crystal's glass bottles are dishwasher safe.
5. The puffing noises made by the machine aren't an indication of carbonation level, only the amount of preesses that you use. So feel free to Fizz as you like :)
5. Short & firm carbonation pushes (approx. 2 sec) work best.
