Heat available when using shade cloth over water? (stream, sound, robot)

[Kitstopher]

I live in on bushland and have a swimming pool that continuously fills with leaves, dust and pollen. I would like to try and cover the pool with a shade cloth, mostly due to the cost and volume of debris the pool is affected by. Can anyone tell me what effect this could have on solar heating of the water? Most shade cloths have UV ratings but no IR ratings and most posts I have read indicate that UV does not affect heat contact. Any serious response or link greatly appreciated.

The pool will be significantly cooler. In south Florida, our pool was open to the sun, the neighbor's was in a screen enclosure and was always cooler. If yours is a standard in-ground pool, invest in a Jet-vac or other robotic pool cleaner. Ours had nearby Poinciana trees constantly dropping leaves into it, and that vac was the only tool that kept things clean. They are about $700 or more now, but worth every penny.

We upgraded to a flowing year-round stream. What happens in the stream stays in the stream (or gets flushed downstream after heavy rain).

Harry, thanks very much for your advice. I think you must have a really neat set up with a stream incorporated! Greetings from downunder

Is there any sort of clear covering that would let solar rays through and still filter out leaves and debris? A plastic of some sort, maybe?

Greenhouse plastic. It is noisy in the wind and subject to being ripped off in high winds and so on. (Builder's plastic doesn't have the transparency. Painter drops don't have the UV blockers and will fall apart in a couple months.

That's a great thought, thanks. I'll have to look into it further. I went to "Eden" in Devon, UK, that sort of thing would be great but the $$$$. Thanks for your idea.

Thanks for the thought mate. A directional, shedding spiders web might be a great MIT project. The greenhouse plastic sounds good too. I feel a little silly posing such a simplish question so I really appreciate the reply.
