More expensive shade for your pool could be some nice Aluma Lattice, a retractable awning or an aluminum awning. Dome and shade screen structures also offer protection from the sun. The pool below was built first and then the deck, screen room and awning were built around it. This gives maximum pool shade and a lot of protection from bugs and other elements.

This is a nice inexpensive pool shade solution for all you Intex pool owners out there.
This could get a little more expensive but look at how nice it looks. The expense would be in the mounting poles, not in the shade sails themselves.
