    Strange white film - out of nowhere

    Saltwater pool, about 40Kgal

    Opened a few days ago - not too dirty; chemistry wasn't bad at all. Shocked it.

    Next day, had cleared up nicely; swept and vacuumed. Added salt to get to 3000.

    Next day, all was well; turned on the chlorine generator.

    Today, all is well, water clear; chemistry is great (Hardness 250, TC 3, FC 3, pH 7.2, Ttl Alk 80, Cya Acid 30-50).

    Turned on heater. At 1pm, 56 deg. At 6pm, 71 deg and rising.

    And now I have a thin, white film on the surface.

    ???

    Any help is appreciated.

    Welcome to TFP!

    Is it foamy? It looks like foam from algaecide.

    Hi; thank you!

    It was not foamy.

    It did go away a day later. As the heat was the sole "new" thing I changed, I have to believe it came from that.

    I guess I wasn't paying attention to weather, either, but as I say it's crystal clear now, and it was just a day after posting.

    Thanks for the reply!

    Looks like pollen. Do you have film of pollen on your car or outside table?
