Thread: Foam problem

  1. Back To Top    #1

    Foam problem

    Vital statistics: FC 4.7, CC ?, pH 7.3, CH ? CYA >10

    When opening the pool in late spring (middle of May) I shock the pool and then add some algicide. There is usually a fair amount of green algae. This year a day or so after I added the algicide I had foam covering almost the complete pool. The stuff is on top of the water so the filter cannot take it out. I am at a complete loss as to how get rid of the stuff. Can anyone help?

    Most likely it was the algaecide. The skimmer should be picking it up, and the chlorine will eventually get rid of it.

    Yes, a lot of algaecides will leave a scummy-looking foam on the surface.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
