Can you over Chlorinate?

Thanks guys. My pool is about 25K gallons. The chlorine level is still at 30 ppm and the water has gone from cloudy green to a dull blue (I can see the bottom of the 4 ft but not the 7 ft). I will backwash now and monitor.

What kind of filter do you have?

I have a Hayward Sand Filter (240 series) with a 1 hp pump

Many of us on the forum with sand filters routinely (after backwashing) add a little DE to our filters. It seems to help the filter catch more stuff. You only add enough to make the pressure on your filter rise by 1 psi. Premix it with a little water before pouring it in the skimmer. It will usually take 20-30 minutes for the pressure to rise, so wait a bit after the initial dose before deciding if you need to add a little more. It might help clear your pool faster.

Looks like you have killed the algae - so it will need to filter out. Keep your chlorine high until the pool clears - it will clear-up quicker that way. You can try turning off the pump to let it settle - then vacuum to waste (if losing all that water isn't a problem).
