Thanks guys.

I bought a house four months before with a pool in it. It had a leak and the former owner fixed it for me and filled it with water. He told me that I had to put chlorine in it. I tried chlorine and other stuff but could not got it in usable state. I just did not have the time to pay attention it any more. Now winter is coming and in Montreal, the temperature could go as low as -30C. The pool is filled with water but it is not use-able. What should I do? Just drain the water out of it? If yes, how? What about the pump, hoses etc? Should I remove them and place inside or just leave them outside. any other suggestions/ guidance would be appreciated. BTW, I do want to use it next summer. Thanks
