Los Angeles, CA
I love these people! When I take a water sample in they test it and sell me what I need and nothing more. My pool was clear all year long and I am convinced there were the reason. In the last I have gone to the national chain pool store on Laguna Blvd. and their solution to many problems was to drain the pool and start over. Never done that due in large part to all clear. Today my pool is "All Clear". I love these people!
