This may seem obvious to most, but I have never owned a pool before and wondering about the necessity of a cover. We are building a rectangular shaped pool and initially thought an automated cover would work. Well PB said it would run ~$15k which we thought was excessive, so we nixed that idea. Looking into Katch-a-Kid nets now, but I'm wondering if we really even need a cover. We don't have a lot of trees in our yard to shed. Our kids are good swimmers and we don't have outdoor pets. We live in the south where it is warm 9 months of the year so we will get good use of the pool much of the year. Tell me, what am I missing? Do we really need a cover?
