Hello all. I'm Michael. As the title says, I'm about to have a pool!!! We should be moving into our new place at the end of this month. I'll update my profile after I have all the details about the pool. It is an inground vinyl liner pool somewhere between 18X36 and 20X40. The first is what the owner said he thought it was, the second is what the PB said it was. They also said it had a pool frog system, and it has a SWG, so that's why I don't know if they have all the facts straight. Maybe the owner put the SWG on it after it was built. It's 5 or 6 years old. Anyway, I'm trying to absorb all I can from this site. After we move in, and I see what kind of test kit has been used, I may have to purchase one of the recommended ones. I strive for perfection in most everything I do, and past experiences with bad pools will keep me on track for keeping this pool immaculate. I can't wait!
