Hello!
I’m helping a friend begin to maintain her own pool. She has a Pentair clean and clear 320 filter. I have a sand so some things I’m unsure of. The opening was hard as she had a temp cover so it was swamp like! It was opened by a pool company this year. We are still working on the water balance.
The filter pressure is now 20. I’m unsure if we need to clean the cartridges and if so how? Also her salt is not working so the maintenance people last year added a chlorinator instead.
Any idea why it’s wet in the pic below?
Any tips or tricks on this filter?
Thank you in advance!
