Painting it black seems a little radical I think, Building a
greenhouse around it? I don't think so. It is always sunny here, but
still, at night thw water cools down a lot so I still need a small
heating system for "winter" months.
Nobody knows af a simple design?

mayby next time try to build your pool in thermos technology
and provide foamed polysterene cover at water-level at night
it doesn't warm the water, but makes water to last warm longer.

Black landscaping plastic sheet.  Only if you have a fence and NO CHILDREN.
You can always buy a the bubble sheets sold at pool supply stores. I had one
for several years. It does work but they only last a couple of years here.
Phoenix area. UV kills them

I saw a pool in Tahoe once with black ping pong balls. I doubt that I could
afford all that would be needed.

Unfortunately cheap and solar really do not go well with each other.

Do not bother with the black paint. I knew a guy that put small brown tile
in the pool to warm it up. Never helped cost a fortune.

Jan, there will be lots of simple systems which you could make.
If you can put some solar panels below your pool, you will be able to
use convection to make the water flow. If not you may need a pump.
If your pool already has one, you will be able to use that.
One of the more simple methods is a long coil of black alkathene
(spelling ?) pipe sitting in the sun. The other is a home made solar
panel with a glass front and metal back and copper pipe inside. I'm
sure if you do some searching for things like "diy solar panels" or
"homemade solar panels" on the net, you will find some plans.
If you don't, let us know and I'll have a hunt too.
These systems will allow you to raise the temparature of your pool,
but it is worth investigating covers to reduce the heat you lose via
radiation, especially at night.
