    Default Filter Pressure question

    First post here so bare with me..

    I have a Penair 4000 Series™ Filters. salt pool, chemicals are perfect (dont have my readings in front of me)..

    I cleaned the grids,tub and put back together (first time). Now I'm noticing my pressure building quick..

    Normally pressure would be 10-12 psi, once it would get to 18-20 (three months), I would back flush, reapply de and it would be fine for months..Now after completley cleaning grids and/or backflushing it will reach 20 in 3 days

    I had never cleaned the grids myself until this time and wondering if I did something wrong?????

    Water clarity is fine, chemicals etc...

    Thanks

    Something from your water is plugging up your filter......algae is my first thought. Test numbers posted might give another clue.

    Thanks I will post my latest readings when I get home.. Does the algae have to be visible??

    I did have a low chlorine problem 2 weeks ago, but never saw algae..
