Pool repair in Chandler Arizona - Filter grids

A customer contacted me recently in Chandler Arizona over his pool starting to turn green. The water chemistry tested good, and there was plenty of water flow running through the filter, so I inspected the Pentair 60 square foot DE filter to see if there were any issues with that.

After cleaning the grids, I saw there were large holes in them and that a pool repair was necessary, replacing all 8 of the DE grids. DE grids tear when they age and it is normal to replace them after 6-10 years of use. When DE filter grids tear and large holes form in the material, the water is not filtered properly and the pool can easily turn green.
