When we started putting the D.E. Media and Filter Aid in the skimmer our PSI was 19. The first pound dropped the PSI to 15. The directions say to wait 5 minutes if the pressure hasn't raised 1 psi to repeat until it does. We have done 6 lbs and the pressure is remaining the same. The pool is REALLY milky now and I'm afraid to put any more into the skimmer. The pressure never did raise, only dropped. What are we doing wrong to optimize the pressure output of our sand filter?
This could be a clogged pump basket, clogged impeller, clogged pipe or clogged skimmer that won't allow for your PSI to rise. You can also check or troubleshoot your filter if it is a problem caused b filter default i.e allowing water into the pool without filtering it causes PSI to rise slowly, reduce or stop rising completely. If all is okay, some filters take too long like weeks before the PSI rises but will eventually rise, especially if you have a large filter.
