CYA Through the roof?

[swilson]

Will it be accurate if I just double the sample from the pool and multiply the reading by 2, or triple the sample and multiply by 3, etc?

No, if you double the sample from the pool, then you actually have to divide your result by 2 instead of multiplying.

The sample from the pool should be diluted 1:1 or 1:2 with water that doesn't contain chlorine for the test to work--and even then you're going to lose some accuracy with each dilution...
