Make sure that your generator is producing enough chlorine, then brush the "slime" off of the walls with a plastic brush for a liner pool or steel for concrete pool.
If your chlorine level is low you need to turn your generator up or perhaps you salt level is too low and you need to add more salt
If you own a gunite swimming pool and it is empty and you are attempting to remove salt build-up, you can acid wash the walls. Mix up Muriatic Acid 4 parts water to 1 part acid and brush down the sides and bottom. Follow up with the garden hose. If the pool is full and you are trying to get rid of the build-up, you may lower the pH & Total Alkalinity below the acceptable range and maintain those low levels while brushing down the walls and floor with a steel-wire brush (gunite pools only) for the better part of a week. Then raise those levels again and start adding a stain & scale preventative chemical weekly to prevent that from happening again.
If it were "salt" it would brush right off. What you are describing is probably a combination of salt and hard water deposits IE: calcium.
There are products sold in pool stores that contain acid that will help dissolve the deposit so you can scrub it off.
If the build up is heavier you might try a pumice stone.
Failing that you will probably need a professional. The old school method is blast with glass beads. A newer safer method is power wash with mineral salts injected into the water stream.
remove the salt
Scrub it down with fresh water and a stiff broom or brush
The salt system has nothing to do with D E returning to the pool. You have a damaged filter element or a bad o-ring or seal in the back wash valve. You have to disassemble the filter and remove the filter grid assy to determine damage to grids. k
You can try the following cleaning solutions; muriatic acid, bleach solution and battery solution.
My experience is that the stains will go away by themselves, through the effects of the chlorination of the water. Does not matter if the pool is a salt pool or fresh water pool. If the pool has a plaster finish, brushing the stains with a wire pool brush will speed up the process.
Remove the salt chlorinatorand stop adding salt, then revert to your prefered method. Ozone is becoming very popular now.
Remove some of the water and refill it with fresh water.

The sumo sprinkle salt around the ring. It is a part of the purification ceremony at the start of the match.
First, find out what the stains are. Iron staining? Stain from using Morton System Saver salt pellets? Algae? Your pool service man should be able to tell you. Then take the appropriate action to remove - ask your local pool shop or pool service person.
