You can get a screening / enclosure covered.

You can get a sun visor ... we obtained from:

The largest square.

Find a large gazebo enough to fit around the edge of the pool or a builder / carpenter to build you a canopy so short.
If you are low on money (if you have a pool, then I bet you do little about the species, but) you could set up two washing lines on each side of the pool and set a darker material each side and above to create a shaded enclosure

put a tarp over it

Church teaches u its ok

Do not worry about the shadow, just to bathe at night!

you might get something tries to set him (not like a tent, a tent, but has no sides), you might get a great of them and it should help

UNBRELLA? AUWNING? Duct Tape?

find a gazebo, prices are falling. they have at Target, Wal-Mart and K-Mart.

If you want something you can do yourself, get a fabric that work for an awning. You have to measure the surface and find where the best local fabric stores. Yo could sink a few 4x4 posts on each side of one end of the pool. Hem each end of the fabric and insert a member of the Red Cross to stiffen it (like a small stick of wood at the back of a store). Once in place. you have a shady end of the pool and the sun can still warm the water to the other end.
