Sand can easily be removed from a pool by renting an underwater vaccuum from any local pool company. Rentals are typically about $40 per day and is certainly a lot cheaper than draining your pool and refilling it. Alternately, you can call your local pool company and they will charge you about $100 to do this for you.
I had the same problem. And you know what i did?! I bought package of beer, in it there are 20 beers and i told my friends, if the pool is clean of sand by 12 o'clock everyone gets 2 beers and if it is clean by 5 o'clock they get 1 beer.It was cleaned in 11.
There is no reason that a good pool vacuum cannot be used to suck the sand from the bottom of the pool. If you need to, take off the head and place the hose directly over the sand to increase suction. Both methods should restore the sand into the filter.
first dry your pool.let it dry for 2 days.Use shovel to remove these sand.Then mob the floor with cotton material which is not wet.This enables the sand to get cleaned completely.The best method may be to call in official cleaners to remove the sand.Clean only on hot summerday for good result.
