Anybody out there have the Aquarium Pharmaceuticals KH test? I managed to lose my instructions for it... so I have a bottle of test juice and no clue what to do with it.
I appreciate the reply, and I did actually try that first... more than a week ago. However, I still haven't heard anything back from them and I'm beginning to suspect that I never will.
So since that didn't work, I thought I'd take a chance here to see if anybody else has the same test. (And yeah, I know their tests aren't held in very high regard around here, but it's all I have right now until I find a suitable upgrade.)
1. 5ml aquarium water (wash w/ test water first)
2. Add KH test solution one drop at a time. Count number of drops. Invert test tube several times between drops. Solution will be blue from start. When it turns yellow the test is complete.
3. Number of drops = the dKH of the sample.
