We live in the desert, and I live near farms. My pool seems to alwasy have dirt in it. I turn the pump on, brush all the dirt to the main drain, and the dirt stirs up in the pool. After I let it sit a minute it seems that the dirt goes back to right where it started. Spread out all over the pool. I can brush this thing all day long, and it doesn't seem like the dirt goes away.
What am I doing wrong?
