My family has always come to Leslie's for all our pool needs. They carry everything you will ever need to keep your pool sparkling clean. They also will test your pool water for you (free, I think) if you bring in a sample. The sales associates are always very helpful, and if you describe a symptom for them, they will come up with a solution, probably in the form of more chlorine. They also carry a selection of inflatable chairs and other fun pool accessories. Great place!
