Hi!

I am planning on closing my pool next weekend, but I think my pool filter is at a point where it is due for a backwash. I would hate to backwash and then waste adding DE back to the filter because I plan on taking the DE cartridges out for the winter. Am I able to to do the backwash and remove the cartridges and then go about closing the pool as usual without the cartridges in the filter?

so in short can I shock my pool and run the filter for a day without the DE cartridges inside the filter, or could I backwash and shock the pool the day before, and then run the filter without adding DE for a day?

Thank you!
