Hi,
I have a red sea co2 indicator whose instructions state to use aquarium water and a couple of drops from the provided solution. However, I read in some post that the co2 measurement is inaccurate when used with aquarium water. Instead they suggest to use a 4kh solution. Is their a way I can make this myself? If so, please explain what I need thank you.
