工具:
(1) KH 4dH 標準液:6公克小蘇打加入1公升的純水,再取其10ml和490ml的純水混合即可。
(2) CO2監測器與指示劑(溴瑞香草藍)
(3) PH 筆
(4) PH, KH, CO2 對照表
作法:
(1) 適量4dH 標準液與3滴指示劑在CO2監測器中混合置入水族缸裡。
(2) 由指示劑的顏色依對照表中KH4dH一列讀出CO2 ppm 濃度
(3) 以 PH 筆測出水族缸的PH值
(4) 在對照表中找到 (2)&(3) 的值所對應到的KH值
舉例:
指示劑綠色,得到CO2=11.8ppm;PH筆測得PH值=6.4,查對照表 CO2=11.8與PH=6.4出現在第二列得到水族缸的KH=1
