Richard320 said:Try doing the overnight test using 25 ml of water. Then each drop is only .2ppm. So even if you are off a bit watching the color change, it will only be .2 not .5 difference. With low CYA probably still, your daytime loss sounds reasonable. The kids getting in probably account for the rest of it.
