Hello Everyone! My two daughters and I are very new to pool ownership so hope to learn a lot from your forum. Thanks for having us. We actually bought the house we live in now because of the pool. We have a 21' x 41' in ground pool that is 8' deep end and 3' shallow end. It has one skimmer and two return jets. The deep ends has a diving board and a slide. This year we are trying filter balls instead of sand - crossing fingers they work as good as the reviews claimed. I have the hardest time determining what color my test strip land so also am trying an app that lets me scan the strips - hoping that will help solve some of the mystery of "all the shades look so similar which one is my water". Good night and hope you all have a wonderful Easter weekend.
