At the end of the day my pool had a good solid chlorine reading then the pump shuts down at 5 pm, In the morning there is no chlorine, what to do? where did it go. how do I fix this
Hi TheReefManiac,
Could you let us know your Cyanuric Acid (CYA) levels? CYA helps prevent your chlorine from burning off by sunlight and many times a low CYA level will cause your chlorine to be depleted quickly. Also if you could post any of your other water chemistry levels that would be helpful.
Thank You
Patrick
