So why can't I keep the pollen off the bottom of my pool??? I clean the filter when I put it in...I clean it two or three times per summer. I don't know why I can't keep the bottom clean. I vacuum it up...Clogs up a skimmer sock...and then two hours later...all over the bottom of the pool again. And I repeat...you could drink my pool water.
Chlorine is always between 4-7 ppm
CYA is kept at 40 ppm
pH is 7.3-7.6
Alk is 90 to 110 ppm
ALWAYS. I test the crud out of my water.
Can the pool pass an Overnight Chlorine Loss Test?
Are you 100% certain these are the proper sized cartridges and there is no physical damage to the system?
Pollen should eventually slow down during the season, and any type of properly working filter should be able to clear it.
