Shawn is excellent!! We recently bought a home with a pool and with the labor of moving, we unfortunately ignored our pool for two weeks, making it turn green. Shawn was EXCELLENT! He walked me through every step of how to fix my pool, and even taught me how to clean my pool filters. He was very thorough, and sure enough, my pool was cleared up within 12 hours! I showed up about 10 minutes before closing, and he was kind enough to finish our conversation and not rush through it, even though I didn't leave until about 20 minutes after closing time. I'll be coming back here whenever we need help or supplies! He really is a great guy.
