Hello all, My parents just purchased a house without doing *any* research at all on how to maintain the indoor pool that came with it. Thus, it falls to me (obviously) to help them figure this out. And yes, I also know nothing about pool maintenance. Awesome! Anyways, I would really appreciate any advice you pool masters might have. Here is what I know about the pool: It is inground. Approximately 18 ft long by 15 ft wide (grades from 3ft to 7ft deep). It is a granite pool with a plaster finish. It has a Pentair DE filter system and a Pentair whisperflow pump (self-priming.) It has two wall-mounted returns. It is in an enclosed room at the back of the house, with a few sunlights in the ceiling and a lot of windows. Chlorine is used as the cleaning agent. Obvious questions: 1. How do they test it? Ive seen all sorts of different Test kits (Guardex, Taylor K-2005, 2006, 2006C, etc) I have no idea what they need. 2. How do they clean it? I've been told a pool specialist said there was no vacuum attachment, so I guess they can't use most of the pool cleaners I've seen on Amazon. 3. What don't I know? Do they need other agents besides chlorine to keep the pool clean? Are there any special things with indoor pools that anyone has run into? I've heard it may need a dehumidifier? Again, any help you might provide is sincerely appreciated. If I have posted this in the wrong section, my apologies. Thanks a lot!
