hi my name is Travis I just bought a house in ND that has a liner pool 20x40 pool the deepest part is 5 feet. he pool needs a new liner and probably other things also. It is winter so I am just trying to figure everything out. first I am wondering if I should go ahead and switch it to a salt water pool is that a better choice or keep it conventional fresh water. would I be easier to maintain not sure what is better. I'll have more questions as I go along and get quotes from the dealers up hear. not to many only 2 to choose from.
