rust colored spots on bottom of pool
getting rust colored spots in different areas of pool..mostly in shallow areas and around steps? tried an algea control, no luck! anybody familiar with this problem? it seemed to come on fast when the temp staring rising to 85 degree or more?
Algea or fungus
What you are seeing may not be algea at all. It is probably a fungus growing under the liner.
You can treat it by liberally appling cuprous ferric oxide around the edge of the pool and watering it in well. It can take weeks or longer before you see results.
Super-chlorination or shock chlorination can bleach the rust color out, but will not kill the fungus under the liner. A copper-base algeacide may help, especially if it contains silver too, but don't pin your hopes on it.

did you find the answer?
Did you find the answer to the rust colored spots on the bottom of the pool. I have an in ground pool with the same problem and need help...They won't brush out, and more appeared today.
Rust Spots.......
I have rust spots on my in ground pool also. I took a sock and filled half of it with acid pellets and put the sock over the rust spot. Worked !!!!!
Rust spots
What kind of acid pellets? Did you use the sock as a scrub brush? I have had this for 2 summers. It is like a growth that adheres itself to the pool floor. I have tried to scrub it off but not much luck.
rust spots
no luck on removing the spots...they seemed to have stopped growing when I added "soda ash" to adjust my PH level, but they have not disappeared! Anybody else have any comments on the acid trick in the above posting?

If it is an IG pool it could be rebar poking through. It is NOT a big deal. We recently had our IG pool acid washed and one spot had rust that was rebar - when I heard that I FREAKED. But then learned it is NO big deal and the acid washing would clear it. And it did. No more rust. So maybe your acid treatment did the same thing...

Take a pvc pipe long enough to reach the rust spots and pour muriatic acid down pipe directly on stain. Use a respirator or be careful because the acid is bad for your lungs when inhaled. Then use a metal inhibitor like phosphonic acid or Jack's majenta to prevent the return of your rust spot.

The rust colored stains are most likely from metal in the water. Some towns run flushing in the water supply and if your adding a lot of pool water during this time you will add too much metal in the water. The browning usually hits the plastic fixtures first such as the jet returns, however it can settle and stain any portion of the liner that water settles with less flow. Try concentrated doses of metal out and stir the water with your pool brush.
