What does sand look like that needs replaced? mine only one year old but i have had cloudy water
all summer long.The sand looked new no channels or anything,i have metals due to a heater
i still have metals but the staining has taken place already.Fc is 3 Th is 175 Alk is 120 Ph is 7.2.
I have been backwashing every couple weeks but i may have not been doing it long enough
one or two minutes.Yesterday i backwashed it longer and i the water coming out was real
cloudy or milky about the way pool looks actually.

The sand should stil be good as it lasts about 5 years. You should be backwashing until the water coming out of the hose it clear, otherwise, debris is still coming out of the filter. You may want to look at using a clarifier to clear up your pool.

Like swimnsave, I believe your issue is a water chemistry imbalance rather than your sand. The only way to get to the bottom of that is with the test results.

You did put a lot of sequestering agents in your pool to remove the metals, this could have changed your water chemistry enough to throw it off. Also, I forgot to add CYA to those test results.
