水草情迷

首先唔好意思甘多位又麻煩到大家.其實我已經潛水潛到好深啦但係整出黎既co2都唔穩定..
小弟用1.25L樽.1/4糖.2/4水.1tea spoon 依士.
做過兩次.第一次用左一個星期左右.第兩次只用到兩日..請問有無一條公式嫁?十萬個唔該

有冇check過有冇漏氣

Actually, it is quite difficult to make DIY CO2 stable. Try to note some points
1. is the temperature too low or too high?
2. try to use tank water or old water instead of fresh tape water
3. once you open the container of yeast, keep it in dry and cold condition, like in refrigerator.
