Pentair FNS Plus 60 I am having to clean my filters it seems like every month which seems to me that's to often. Why would I have to clean them so often? After I clean them I have 10 psi and backwash when it hits 20psi. I just back washed last week and now I'm up around 20psi again so I'm having to backwash and clean filters very often.

How are you maintaining your chemistry? Post up a full set of test results.
We recommend backwashing when the pressure rises 20-25% over the clean pressure. If you are starting at 10psi, then you should be cleaning by 13psi or the flow rate drops too much.
Could be algae clogging them or perhaps they are scaled up from high CH and pH.
With a filter that size you really should only need to clean it 1-3 times per year.
