Thank you where is the chart located? My test kit didn’t come with one.As long as your FC is between minimum and SLAM levels for your CYA, based on the FC/CYA Levels chart - and you can see the entire bottom of the pool (swimmer safety) - it's safe to use the pool.
Also I am reading the slam document and how can I find out how to backwash my system and where do I find what my slam level should be?
