So I was getting itchy to use my new toy (TF-100) that I got for Christmas. I decided to scoop out some pool water and run a set of tests.
While performing the CH test, I saw something unexpected and something that I didn't notice with a previous drop based kit. I took the 10ml water sample, added 10 drops of R-0010 & mixed. Added 3 drops of R-0011L & mixed. This is where things started going astray. I could see a color change to pink indicating CH was present, but it didn't look right. For lack of a better description, it looked poka-dot pink & clear. It looked like the pink indicated portion was precipitating out of solution. I left it sit on the counter for a few minutes and there was definitely a separation of the solution.
Just to see what would happen next, I continued on with the test and added R-0012 until endpoint. The color changed to blue, but it was only the pink portion that turned blue, the clear portion of the solution remained clear.
So my question is, does anyone know why the calcium is precipitating out of solution? Does it change the validity of the test?
