Def didn’t use 100 drops on one test but wish I had because of how much I used in the end. I just thought something was wrong.So there are two likely culprits. Your chlorine % or you had a 25mL sample size and 20FC would be 100 drops.
What is the chlorine product you are using?
For testing...
Take care, use 10mL sample.
When you use the reagent, hold the bottle vertical and squeeze VERY gently, allow the drop to form and drop under its own weight. Swirl (unless you have a speed stir).
If you squeeze drops out quickly, they are smaller than expected and will require more drops.
As far as application of drops and drop size, position, etc. I’m following.
