用什麼方法可以測試???

CO2測試濟

睇草既生長情況!
你個缸一秒一泡都夠

I think the "CO2測試濟" is not useful if PH is 6.0. I just brought one, however, the PH of my tank is 6.0. In addition the reading of test shall be read along with the KH valve. IN my case, the KH is 0 or 1. The "CO2測試濟" could not give you result if PH is 6.0 or lower.

Do you understand? The indicator of the "CO2測試濟" looks like the table listed belows:

PH:===6.4===|=6.8=|=7.0=|=7.2=|=7.6==
CO2:-too much | Good | Good | Good | too less
KH:========| 4 - 6 | 8 -12 | 12-16|======

I think a PH meter and KH meter is essential to obtain a CO2 content is PH is equal or lower than 6.

i see .......
thank you
