Hi everyone I'm having trouble with my filter pressure being high and it's irritating me now.
So my pool was a green colored swap so I shocked the pool ( lowered the PH to 7.2 and brought CYA to 30) by bringing free chlorine to 13. Pool was improving but then it stayed the same color for 4 days.
1. I cleaned the filter by hosing the cartidges down (green colored) and added 8 scoops of DE (recommend dose) psi went to 34. No improvements in 2 days,
2. Took the filter apart again hosed it down (brown colored) added 2 scoops of DE (I know it was too little but my psi jumped to 32.
3 (We're I am now) took the filter apart cleaned it a third time and added no DE, and my psi is at 26psi as I type this.
Any ideas as to what it could be?
Also the filters were changed in March and when I cleaned them I saw no tears or holes in the filters.
