Low Range CYA Test Kit ? More Accurate CYA Testing?

[Shocking]

I run CYA 20-40 ppm, which is the bottom of my K2006 testing range. The K2006 appears focused on those running their CYA higher. Is there a kit that covers a lower range?

And for that matter, if the focus were on a lower, narrower range, is there a kit that reads more accurately (e.g., 5 ppm increments) and/or easily?

Even after practicing with reference solutions, I never feel as confident or accurate as I want to be with CYA. CYA testing must be difficult, because I've heard of pool stores having trouble with it. And our health inspector (this is a community pool) clearly struggles to get meaningful data as well.

Thanks!

Taylor sells a view tube that will read down to 20 and is compatible with the same reagents, part # 9193. To do better than that you would need to spend several hundred dollars, which really isn't worth it.

Thanks, JasonLion. I'll look into the Taylor view tube and be satisfied for now with that level of accuracy. I'm pleased to see that TFTestkits (our preferred seller), stocks a similar product.
