Hi Kevin,

If it were my pool I would add several gallons of bleach, run the pump for 24 hrs, and brush the bottom and sides for all I'm worth to get whatever is ailing the water stirred up and filtered out. You say "Cl = 0" . Which Cl reading is that? Free chlorine? Total chlorine? Are you using strips or a reagent kit?

At this point it's moot, IMO, since you have cloudy water and a 0 reading. Something is growing and needs to be controlled.

You wrote this on June 23. Today is the 25th. What have you done over the past couple days and what were the results?
