1. Post a full set of readings on BOTH your pool, and your fill water. (Don't test CYA on the fill water!) Watch the videos (above) if you need to, but please post numbers, not drop counts. If you are having a hard time understanding the tests, watch the videos, and then ask us questions.

2. ID by make and model your pump and filter.

3. List the problems you see with your pool / water in order of concern to you.
