This is my go to store for all of my pool and spa needs. I got "pool stored" by Leslie's in the past when I was new to pool ownership. A&M Corson's has never tried to sell me anything I didn't need and everyone I've spoken with was very knowledgeable. I only use liquid chlorine in my pool and they sell the best available LC (HASA). Returnable jugs for both MA and LC which I love! Less plastic in the landfills!
