Good morning! I have looked and didn't see the answer so I'm hoping someone can help me. I am in the process of slamming my pool. My question is, do you test the chlorine using the normal method? My CYA is about 55 so, for a 15k gal pool, that puts my shock level at 22. That is over 100 drops of reagent for a 22ml sample! If I'm going to test it every few hours - or even a few times a day, that is a lot of reagent. Granted, I bought the big bottle, but I just want to make sure I'm not being a dummy about this. I guess using the 10 ml sample would be about half the drops -or am I thinking of this backwards?

Use the 10mL sample size for a 0.5 ppm/drop precision. That's more than enough precision for a SLAM.
Thanks! 40-50 drops still seems like quite a bit so I just wanted to make sure I was doing it correctly. One more question, is it best to run the filter on high or low while slamming?

Low is fine. The purpose is to keep the water circulating so that the plumbing sees the SLAM level FC.
