We recently purchased a house with a pool that needed some TLC. We took in a water sample to Leslie's and they tested it for us. They told us exactly what we needed for the pool to get it back in shape.
The staff there are extremely helpful, friendly, and professional. It was great to see excellent customer service being provided here. While the prices are somewhat high, it is worth it to be able to get advice from professionals rather than having to guess at what you need.
We highly recommend this establishment for all your pool needs.
