Solar heating for the pool & Oil slicks

[Morristhedog]

I bought a solar heater for the modest 11,000 cubic meter pool in the garden.
Unhappily it slows down the pump so much that the water was scarcely being pumped in the pool, and I was worried about the chlorine tablet not being distributed sufficiently for hygiene reasons.
Currently it is disconnected which seems a shame considering the outlay, and the fact I want a heated pool.
What does anyone else have as an experience in this circumstance?
Why do people cover themselves in creme and oil and then leave it like a slick in the pool? How does anyone get rid of the muck?
I would be grateful for all kind suggestions.

Hi Morristhedog. I'm sure someone will be along in a while with an answer, but you may get a quicker response if you repost in the "managing your pool and garden" section. I know the sun cream issue comes up there from time to time. N

Thank you, I had not realised there were sections.
