Yes you can, however why would you want to?
You will achieve the same affect by simply running the filter through the same filter more times.
If your goal is more refined water, I would suggest changing the filter type.
No, it'll blow right back to the pool which will then make it hard to remove. Sand filters REQUIRE a #20 grid pool filter sand. There is also another product possible called zeolite for sand filters... it will filter finer than sand.
PLEASE DO NOT USE THE WORDS "YOU" OR "YOUR" IF YOU ARE TALKING ABOUT YOURSELF. uSE THE WORDS "I" OR "MY" OR "OUR". AS IN MY POOL XXXXX.
Sand filters are not cleaned with chemicals . they are back washed when required. every four or five years it pays to replace the sand in a sand filter to maintain its efficiency.
No

.017 to .022 silca sand found at any pool supply store New: I doubt that you are going to find .017 or .022 sand even at a building supply place that specializes in sand, plaster, rocks, gravel etc. A #20 silica sand is what is available for swimming pool filters and that is what should be used. .017 sand may in fact be too small for the latterals in a sand filter thus letting small amounts of sand to pass thru to the pool daily resulting in a buildup of dust and sand on the floor of your pool.
swimming, as in a swimming pool

yes you can, the sand pump cleans the pool, making it look amazing!!
One way if you have a sand filters is to use it's waste setting. That directs the flow of water out the backwash line without filtering it.
This sounds as thought the laterals in your sand filter are worn. Laterals are horizontal spokes at the bottom of your sand filter with tiny holes in them that let water through but not sand. After a time the holes get enlarged and start allowing sand through and back into the pool
