I am sure this will be in the wrong area..... I am needing a little advice. I have had a free form plaster salt water pool since 07-08... There is a hot tub attached but separate. We never finished the hot tub, and after my ex husband and I parted ways (he was the builder) I have zero idea on how to finish it. It is all stubbed out. The main thing I am wondering... I have a heater and blower for it. I really don't want to go to the expense of another sand filter and pump. Is it possible to ball valve lines and be able to use the same filter and pump as the pool currently uses? If this is possible, how would I set that up? I am terribly sick of looking at a hot tub that has never had any use. Thanks for any advice.
