Update. I clean the filter with acid. Put DE back in the pool and we will see what happens.

Also just another piece of info, a couple of the grids is collapsed on the top. This happened a year ago when the pump went out. I then replaced the pump and all the grids.

What do you think is collapsing them again? The original motor lasted 6 years and so did all the grids.

ps. the floating feeders are because my salt main logic board went out so I am back to floating feeders.
