About 2-weeks ago I purchased the Taylor K-2006 pool water test kit. The Chlorine test worked as per instructions for the first 1.5 week. But the last couple days of tests, after I add the 2-dippers of the R-0870 powder (using the 25ml water sample), the water is remaining clear (with prior previous tests it was turning pink as expected). The instructions indicate that if the water does not turn pink, then add more R-0870 powder. I tried adding 5 more dippers, swirling with each addition, and nothing. The water remained clear. I also tried it with the smaller 10ml water sample hoping it would save me some R-0870 powder. Still same results. The instructions do not indicate what this means. Any idea what this indicates? Is my pool chlorine starved? NOTE: Chlorine did test okay a week ago.
