By the way, use the 10ml sample instead of the 25ml sample when you test. It will make your reagents last longer. You don't really need readings within 0.2ppm; 0.5 is close enough.

Overall those numbers are just fine! Keep up the good work!
Sweet! Thanks a bunch. I'm going to wallyworld to get some bleach in a few minutes to give it a good shock. We had a gathering yesterday so I plan to hit it with 3 gallons of 8.25% bleach tonight, which should bring it to ~20 on chlorine.
