Review: Great value. Works too
Review: Powerful and Reliable Pool Shock for Crystal Clear Water This 24-pack of Drytec 1-pound calcium hypochlorite bags has been a real workhorse in keeping my pool sparkling. Each bag is individually sealed, making it simple to grab one, cut it open, and pour without mess. I like that the packaging is compact and easy to store in the garage, and the dosing is straightforward—one bag at a time keeps me from over- or under-chlorinating. Performance-wise, this shock works quickly. I usually add it in the evening, and by the next morning the water is clear, bright, and free of that slightly cloudy look that creeps up during heavy use. It’s strong enough to handle algae blooms after a stretch of hot weather but doesn’t leave any noticeable residue once fully dissolved. A couple of things to keep in mind: this is calcium hypochlorite, so it does raise calcium levels over time. That isn’t a problem for me since my pool water tends to run soft, but if you already have high calcium hardness, you’ll want to monitor it to avoid scaling. Also, because it’s strong, I always pre-dissolve in a bucket and add it slowly to avoid bleaching spots on the liner. Bottom line: A reliable, cost-effective pool shock that’s easy to use and keeps water crystal clear—just keep an eye on calcium levels if your pool runs hard water.
