We got a new house and a new pool came with it. How exciting, except for the fact that pools are work and we knew nothing about them. Enter D&L!! "Doc" has the answer whenever a pool owner does not. My pool was as green as a golf course when we opened it, in one day Doc had it crystal clear. You take him your water and he hands you a sheet of paper and tells you exactly how much of everything to put into your pool. He is also great with spas! Pool service guys go to him when they have a stubborn pool too, I have seen them in the store!!
In addition, you can buy any part you need there, big or small. They also have safety accessories, skimmers and even toys and floats and the prices are VERY reasonable.
