D'oh...lost instructions...

[MarkW19]

I've lost the instructions for my carbonate hardness test. It's by Aquarim Pharmaceuticals.

Does anyone have the same test, and/or know what to do with it? I seem to remember you fill the test tube and then put one drop of water in at a time, and turn it over once. Then when the solution changes colour, the number of drops added before it changes colour is the number of dKH...can someone verify this?

I was surprised they had them too. Glad I could help.
