Added the chem clean per instructions. Says to allow 24 hrs before adding carbon or PS and then 20% WC in 48 hrs. well I waited for 48hrs and PS was acting crazy, so I turned it off. Even with the water flow turned all the way down. So I did another 20% WC 48hrs later. PS is still going crazy even after turning it on after 24hrs of the 2nd WC.
