We love the BioGuard products. We found that their products work the best of any we have used.

Worked much better than the cheaper brands at the local big box stores!! Will continue to use each year!

I've been using these chlorine pucks for years now and I always get them from Pool Geek. The product is high quality, unlike the cheapo unnamed brands, and Pool Geek always provides fast shipping.
Excellent delivery. Great savings. Excellent chlorine.
I have only one complaint and that is the price. It has doubled since I began using it. Can you explain this to me? Your service was good and price was slightly better than Amazon, which I checked after ordering as I don't like to order from them. Free delivery was great. What is the actual cost of that?
