Do i fill the container with 5 ml of pool water and the other 5 with tap water that is well balanced with a ph of 7.5 and alc of 90.

If i understand it right i would just have to count each drop as 1 ppm.

Thanks
Ps i have high fc right now and i dont want to waste all my products.

Don't use tap water unless it is unchlorinated well water. Just mix together equal parts (cups, shot glasses, tablespoons or whatever) of pool water and unchlorinated water. Then fill the sample tube with the mixture.
