I bought a curse above-ground pool a year before I sold my house. I started going to Pearland Pool Supply to get my water tested. The service was wonderful, and the advise was always right on. The owner, never tried to sell me something I didn't need and would often let me know what could be done with what I already had. When the curse took effect (lol), I was often in there every other day, and he remained friendly and as helpful as ever. I always felt like he was going out of his way to help me figure out the problem with my pool. We have since sold the house, and I still travel past Leslie's to go to this store for our spa.
Prices are competitive and the service is outstanding. Give them a try!
