Cloudy water too long.

[Old Eagle]

I have just put new sand in my Hayward sand filter. The sand was purchased at Namco. I did a backwash to get any really fine dust out.

It seems to be taking a very long time to clear up my already cloudy water. I have put in algecide because there is a slight greenish tinge to the water. Because it is cloudy, I have added clarifier of the floculant type.

Is there something else I should be doing to help this new sand?
