What does diatomaceous earth do for a pool?

Can you put too much DE in a pool filter?

Too much D.E. will result in the D.E. “bridging” between grids — reducing the filter area. This will make the filter less efficient, raise the back pressure, ruin the grids and make the whole circulation system underperform.
