How to get surface scum in stock tank?

[BobStrauss]

So I’ve got a stock tank pool that I put together earlier this summer. Using the TF-100 kit, I’ve been able to keep the water under control without any algae blooms or anything. Latest numbers are FC 6.0, CC 0.0, TA 60, pH 7.5, CH 200, CYA 50, Borates 50.
However, one ongoing issue I have is with the scum left over from sunscreen after swimming. Our stock tank only has the intake to a cartridge filter below the surface, no skimmer that could pick up what floats on top. I naively purchased a hot tub/spa cleaner recommended on someone’s Pinteresty blog that was claimed to help, but that seems to be floc - which clears up the pool but also clogs my cartridge filters.
Any recommendations on how to deal with this? I’ve tried scumballs but they didn’t seem to accomplish anything.

Bob, if you can I'd suggest avoiding the use of sunscreen while in the pool. I know that's strange, but you have an unusual pool, right?

If this is just a scum line some manual wiping with MyteeMitt or Mr Clean magic sponge and a bit of elbow grease may be all you can do.

Hmmm not the magical solution I was hoping for but thanks for letting me know.
Would it be dumb next year to get a sand filter instead, then just keep using the spa cleaner solution to get things cleared? Does the floc gum up those as well?

Is it all lotion? If so what about tossing a tennis ball in to absorb the oils and changing it out from time to time?

Another thought I had which *may* help is to up your FC a few points to let it help oxidize the oils.
