Per installer of pump one year ago, we completed back washing as needed and only disassembled to clean filter after one year. We installed the same filter that we had installed at our previous property. We have experience and success with this filter and pump. After cleaning the pump 4 weeks ago, the pump is slowing sooner, requiring backwash sooner. Today, I backwashed the filter and flow was good, but perhaps not amazing, phosphates were at 500 due to a pool party yesterday. I treated with PhosFree/NoPhos per instructions, reduced alkalinity 20 points and shocked the pool with 1lb cal-hypo. By evening the flow was barely visible on surface level. Ideally, backwash again 48 hours from addition of NoPhos.
Thoughts? Just seems like filter is already saturated.
Thanks for any help of thoughts!
