Cal Hypo Shock
The media could not be loaded. Product was fresh and priced lower than other vendors. Great for shocking the pool weekly. Leaves water crystal clear, never cloudy.

Works FIne; Dissolves Relatively Quickly
Despite reading all the negative reviews about how it was slow to dissolve; I couldn't get past the low price and decided to give it a shock. I don't get it. It may have a little more dust than the other products I've tried, but I'd be tough to really measure any difference. I worked fine, I always run the pool cleaner after adding shock (for that extra aggitation), so that may be why; but I'll try it again if the price is right.

Easy to use and works great
I would like the bag opening to be easier to open is my only dislike, but I have a 24' round above ground pool and use two bags per week I just walk around the outside edge sprinkling it in as I walk and leave the pump running awhile to disperse it. I wait 15 mins and then use a brush inside the pool to scrub around the sides and bottom to get it evenly dispersed.

Good chlorine for the price
With pool chlorine prices through the roof these last few years, saving a few dollars wherever I can on shock and chlorine is a must to keep the pool clean on a budget. I used this Dry Tec 1-1901-12 Treatment Pool Shock all this summer (2023) and it worked as good as any name brand shock.

Does not dissolve easily
I’ve tried at least 5 different brands of chlorine shock and this one is definitely the worst. It does not dissolve quickly and leaves white particles floating on top and throughout the pool. Because it doesn’t dissolve as well, it requires more bags. Chlorox is cheaper now anyway, it’s a better product.
