Thread: Yellow scum line?

    Yellow scum line?

    Hey everyone!

    I didn't close my pool for the winter, i live in GA and the weather isn't too bad over the winter months so i decided to keep it open due to the cost of having a liner installed etc. Anyway, ive kept it up, and we have had a lot of rain this last few weeks, i noticed 2 days ago a ring around the pool that is yellow, i brushed the sides and it comes off no problem, looks kind of powdery. Today, its back!

    Any ideas?


    I've a gunite, in ground, 18x36, sand filter.

    Hi there just-me and welcome to TFP!

    Dunno what the yellow is, but in my pool it is pollen or DH just sanded some more boards nearby Either way, the skimmer socks take care of it for me.

    You're done SLAMing when:

    Puzzling. Must be something airborne. I can think of nothing that would precipitate out yellow from your pool. However, I can't imagine any pollen in Georgia in February, either.

    Certainly doesn't seem like a big issue but I'd be curious if you find the source.

    You might want to google the pollen index for GA to check. Ours is almost medium today which could account for what little bit I saw this morning, but DH did just sand some boards yesterday, too.

    I've got the same thing here in NW Florida. It is pollen no doubt and I agree it is probably oak tree pollen. I don't think it will last for too long though, but the oaks are about to shed ALL of their leaves in a few weeks Guess I'll be scooping leaves out for a while. The good news is that they shed fairly quickly and once the new leaves show up, I won't have to deal with 'em during the swim season.
