Pool store, huh?

I was looking for R-0871 and a pool store told me that I didn't need it. Just use purified water to get a FC reading above 10 with the R-0001 and 0003. Huh?

I'll do the TNT version TYVM.

In a pinch, you can use bottled water to get a rough idea of a higher FC level. Just dilute your pool water with 3 parts purified water and test the mixture. Multiply the reading by 4. Accuracy suffers unless you measure very well or use a scale to create your mixture.

Ok, thanks!
