What causes the foamy scum on pool water ? – Home & GardenReport
TANNING OILS, BODY OILS, SUNBLOCK, SOAPS AND HAIR CONDITIONERS, WAS THE ANSWER I GOT FROM THE POOL SUPPLY PLACE THAT I USE. SEEMS THE SOAPS BREAK DOWN THE OILS ENOUGH SO THAT THEY PASS THROUGH THE FILTER AND THEY FILM UP ON THE SURFACE. IF YOU NOTICE THIS BUILD-UP IN AREAS OF YOUR POOL WHERE THE WATER MOVEMENT IS POOR THEN I’D RECOMEND TELLING EVERYONE TO RINSE OFF THOUROUGHLY BEFORE HOPPING INTO THE POOL “DIRTY”.
We have just run into this problem as we were opening our pool. We accidentally put too much Algaecide in our pool. I know know from other sites that too much Algaecide will cause a pool to foam up.
On the down side, I am still looking for an answer on how to clear it up.
It only goes to show as above . . . . . READ THE LABEL ON THE PRODUCT YOU ARE USING.
After all this time no one has suggested running the filter longer!
