Love This Shock
I only use GLB Shock in my pool. Dissolves easily and keeps my pool crystal clear.
Great product and amazing price point
I had been looking for the highest % of cal hypo without having to mortgage my house to get it. Super Sonic is perfect and Pool Geek offers it at such a great price point. I have purchased several boxes of Super Sonic this summer and will continue to do so. Pool Geek also offers other fine products at great prices.
