You need to get all the debris and junk out of the water you can. Keep at it.

Putting in bleach was not a bad idea. If the pool is small as you indicated (I'm guessing 10,000 gallons) then that would have been a good starter--but you'd have to put it in repeatedly.

Have you filled the pool with fresh water? I'm guessing it was low and you did or the pump and filter wouldn't have been able to do anything. You can drain off 3/4 of the water and refill. Leave at least a foot of water in the shallowest section when you do that--don't drain more--you know why.

You WILL need to test your water for what's in it. We can only guess and that's not the best thing for you.
