Here is what you had said:

Mix a cup of pool water with a cup of distilled water and use that to run the CYA test again but multiply your results by 2. Glad to be here too by the way.
100 is the highest number on the tester so if you get a reading of 100, it means your CYA may be 100 or any number past that. So, if you do a dilution, it can help us to get a more accurate reading. (Of course, if your CYA is over 200, you'll still get a reading of 100 and may need to dilute the sample further.)
