I did a back flush earlier today, and afterwards noticed that D.E. was returning into the pool from the return lines. We opened up the filter and noticed that the grids were in pretty bad shape, with a few large holes in the fabric. I ordered a new set of filter grids, but in the meantime, is it okay to swim in the pool? The water is a cloudy, but I can see the bottom of the shallow end. We also turned the pump off so more doesn’t come back into the pool. TIA
