I usually use bio gaurd 3 step, I went to a store he sold me the surf side brand they last a week blah, blah I put one in at 6:15 yesterday almost no chlorine in the pool. Today I go out at 5pm shut filter off my tab has dissolved chlorine level is through the roof. Ran hose to add a bit more water. Should I keep the pump on to prevent liner damage due to high chlorine? Next time I'll break the tab up and use a quarter of it. It's an intex ultra frame pool.
