This Drytec product was shipped and arrived very quickly. It was nicely packaged with no rips or tears. The directions are easy to understand and I would definitely recommend this to all who need a disinfectant for the pool or other things. All in all a great product once again! 🙂

Dry Tec to disinfect water in an emergency

I bought this product (Dry Tec 68% Calcium Hypochlorite Granular Swimming Pool Shock - 1 lb) to keep on hand to disinfect water to drink in an emergency. Easy to store and use- Dry Tec is a brand I have used in the past and trust. A little pricey for what it is but they do ship it right to your door and I did not need a 5-gallon bucket of the stuff. Yes- I would recommend Dry Tec in the 1lb size. Good to have in an emergency for water you might not be able to boil.
