it depends on what type of pool it is, you might not have to drain it , only marcite pools can be shocked with 5-6 gals of liquid chlorine to clear split pea soup type water, whereas, vinyl or fiberglass, you could never use that much chlorine and you would have to use other steps to clear and in some cases yes, only draining will work
Clean your filter!!
To maintain a hot tub on a deck, regularly clean the filter, test and balance the water chemistry, shock the water weekly, and drain and refill the tub every 3-4 months. Additionally, keep the cover on when not in use to prevent debris buildup.
How large is the pool? Vinyl or plaster? Super chlorinate with 12% liquid chlor. -- about 4 times what u regularly use. Filter 24/7. Adjust pH when water starts clearing. When water is clear and I mean where you can read a quarter sitting next to the main drain grate at the deep end of the pool, cut back filter run time to 8 to 12 hrs. k
Here's a quick tip on chemically cleaning or killing the algae living in the sand in a sand filter. The next time you shock your swimming pool, poor the shock or bleach in the skimmer. This will provide a very high level of chlorine in the filter for a very short period of time. Long enough to kill the stubborn algae living in the filter but not long enough to hurt your plumbing.

I use the Intex pool startup kit. It has sanitizer, pool test strips and shock. Add Sanitize which is granular chlorine. If you have a pool brush, brush pool. I actually use a mop. If its really dirty you may have to get inside pool to mop, in which case add Sanitize after. Then run filter for 20 minutes and use test strip to check pH & alkilinity. If not right pH add another dose (booklet in kit says how much per 500 gals of water)and run filter another 20 min. Then add Shock and run filter 4-8hrs. If you don't have a filter, then you probably have to drain, clean with regular liquid bleach & mop then refill.
SHOCK!! Its a powder you can buy at a pool store or chemical store.. its chlorine in powder form, you just dump it in your pool stir it up a bit, wait a day or two, and the pool should be clean.
Rephrase the question. What type of shock have you used? Is it a calcium based shock treatment? Supply more info.

When it is slippery on the bottom it is normally algae, all you need to do is give the pool a good shock. That will also clear up the cloudy water. If you have a 10,000 or more gallon pool then you need to regularly shock the pool 2-3 times a week. Especially if you have a heavy bather load, or it frequently rains in your area. Also remember to add shock after the sun goes down, or the sun will just eat up the shock. If this doesn't help then you may need to check out your filter and make sure that it is running properly. If it has been a while since the filter was cleaned then perhaps the filter just needs a good cleaning.
Yes; mix the shock with water and pour it into the pool directly in several locations and run the filter.
Lubricate, seal, clean , cool, absorb shock!
