水草情迷

小弟買左個玻璃長期ph測試器(Drop Checker)
但不見了說明書
想問黄色代表乜? 水中 co2 過多定過小?
點解就算水中ph值轉了很多,(用ＰＨ paper 度 7.幾)
但等了很久,個測試器仲係唔轉色(黄)?
thx~~

If you are using kh4 solution in your drop checker, then yellow means too much CO2, green is okay (about 30ppm) and blue is too little.
The colour only depends on the amount of CO2 in your tank and is independant of the ph and kh. For details, you can visit Tom Barr's website.
