Hello Forum,

Any help would be appreciated. I struggled with chemicals last year and would like to keep it clean this summer!

Above ground 24', Vinyl, 16.500 gal. Hayward Sand filter S210T2580, Hayward 1/5 hp pump - CA02-15

hth 6-way drop test results:

Chlorine test - clear, non existent?
pH - 8.0
Alk - 150+ ppm (stopped after 15 drops)
Calc Carb - 150+ ppm (stopped after 15 drops)

Thank you!
