When a faucet is opened, water is drawn from the holding tank through a very large carbon filter into the house lines. The chlorine in the holding tank is around 8 ppm. What I draw at the sink is 1 ppm or less.

When I have to top off the pool I turn off the chlorination system and use straight well water. We don't have metals in the well and its alkalinity is right around 50 ppm, perfect for my pool. I usually adjust the FC to 5 ppm after a refill and let it drift back down to its normal 3 ppm.

Didn't mean to highjack your thread, Jacob. Having a good test kit is really very useful when you're using well water.
No worries. Pretty interesting actually. I'm not sure how mine works to be honest. All I know is that I have to dump water softening salt crystals into it every few months...

So, should I be testing my well water for alkalinity? I'm not planning on filling my pool with it, but will probably supplement with about 5000 gallons over the course of a few days. I need almost 24000 gallons, and (3) 6500 gallon trucks will give me 19,500 gallons. I plan on topping the rest off with my well water.
