I went to test cya (7.5ml water, 7.5ml reagent) but when I poured the last drops of my R-0013, there was only about 1/2 of the 7.5ml the test calls for. But I went ahead with the test just to see if it registered. I had added CYA a couple days ago estimated to bring it from 30 to 45, (per PoolMath: 20oz-wt CYA for 10k gallon pool) so I was expecting some change. The test with 1/2 the reagent actually showed me to be near 50 now.
So, my question is whether the test is possibly valid, or would it necessarily yield lower results than actual using reduced amount of reagent?
I won't have more reagent 'til next week, so should I dose liquid bleach based on CYA=50 until then?
