i have an inground 21,000 gallon sand filter. just starting opening this week..it is still just a little cloudy and looks a little dingy. i vaccum daily. you can see the bottom, but i have been trying to keep the clorine high, it has dipped some when i cannot keep a constant check on it. ta is 80, clorine is above 5 (i am out of reageants for my taylor 2006, waiting for those to come in). at this point i cannot test for cya, but it has always ran high. ph is high 7.8. do i just continue to add bleach until it clears and do i need to adjust the ph now or wait until i stop keeping the clorine high?
