1-1901-12 Calcium Hypochlorite Pool Shock 12-Pack Review: Reliable Pool Cleaner?

Keeping a pool clean and clear is always a bit of a project, so we decided to give DryTec pool shock a shot. Over a few weeks, it did a solid job fighting algae and knocking out bacteria, and the water looked fresh and balanced most days.

It usually dissolves pretty well, though sometimes a few stubborn granules settle at the bottom and need a quick brush.

Applying the product is straightforward, but it works best if you keep up with regular use and maintain your pool chemistry. We kept the water clear, but had to pay close attention when testing chlorine levels since this shock can throw off some readings compared to others.

Overview of DryTec 1-1901-12 Calcium Hypochlorite Pool Shock

We tried DryTec pool shock for a few weeks and noticed it really kept our pool water clear and free of algae. The granules dissolved pretty well when we spread them out, especially in the deeper end.

Sometimes granules settled, so we brushed the pool bottom to help them disperse. Keeping pH and alkalinity in line made a big difference in how well the shock worked.

One thing: you need to test carefully, because this stuff can mess with chlorine readings, and some test kits might not catch everything.

Key Features

After using this pool shock ourselves, we think it strikes a decent balance between effective cleaning and convenience. It covers the basics, but has a few quirks worth mentioning.

Powerful Bacteria and Algae Control

This shock really goes after bacteria and algae, which helps keep the pool safe and looking good. We saw less algae and the water felt fresher.

You’ll want to keep an eye on pH and alkalinity while treating, since those need adjusting for best results.

Fast-Acting Granular Formula

The granules dissolve fairly quickly, so the shock kicks in faster than some others we’ve tried. You don’t have to wait ages before jumping back in.

They don’t dissolve instantly, though, so stirring the water or brushing after adding helps avoid residue.

User-Friendly Application Process

Using this shock is simple enough. We followed the “one bag per 10,000 gallons” rule, which made things easy to measure.

The package size works for storage and dosing, but you do need to measure carefully—overdoing it can mess up your pool’s pH.

Reliable Water Clarity and Safety

With regular use, our pool’s water stayed clear and safe for swimming. We saw fewer algae spots and less cloudiness after a few weeks.

You still have to monitor water chemistry to keep things balanced, but when you do, it’s pretty reliable.

Summary Table

Routine Pool Maintenance Benefits

Keeping a pool clean takes regular work, and using pool shock like this one really helps. When we added the right amount on schedule, the water stayed clearer and felt fresher.

It did a good job controlling bacteria and algae without much hassle. We found it balanced chlorine levels well, which is crucial for safe swimming.

Dosing needs attention—too much can push chlorine too high, so measurements matter. It dissolves fast enough that you’re not waiting around to swim.

Handling and Storage Tips

When working with this pool shock, we made sure to keep the granules dry and sealed. Any moisture can cause clumping and mess with how well it works.

We wore gloves and avoided breathing in the dust, since it’s a strong irritant. A mask helped too.

It’s best to store the shock away from organic stuff and metals, since it’s a strong oxidizer and can cause problems. Labeling the container and keeping it away from kids and pets is a must.

Honestly, dry storage, gloves, and clear labeling made things easier and safer for us.

Pros and Cons

After a few weeks with this pool shock, here’s what stood out to us:

Pros

• Effective cleaning: Our pool water cleared up fast, sometimes overnight, with the right dose.
• Good for tough algae: It handled algae, even with lots of leaves or debris around.
• Easy dosing: One bag per 10,000 gallons kept things simple.
• Consistent chlorine: Helped maintain chlorine at useful levels with little guessing.
• Quick dissolving: Dissolved faster than some others we’ve tried.

Cons

• Doesn’t always dissolve perfectly: Sometimes it took a bit longer to fully dissolve.
• Chemical effects can be unpredictable: Some folks say it might add bromine, which not all test strips detect.
• Handling precautions: Since it’s a strong chemical, we had to be careful measuring and adding it.
• Packaging size: The 12-pack is bulky if you don’t use it often, taking up more space than expected.

This pool shock keeps water clean and clear, but you do need to pay attention while using it.

Customer Reviews

Most people seem to like how well this pool shock clears and maintains their water. Clarity and algae control are consistent, especially with weekly use.

Many say it dissolves better than similar products, making it easier to use. Some did notice slower dissolving times, though.

A few mentioned that standard pool test strips might not catch all the chemicals it adds, which can be confusing when testing water. For anyone needing reliable calcium hypochlorite, it looks like a solid pick.

Pros:

• Effective algae control
• Keeps water clear
• Easier to dissolve for most users

Cons:

• Dissolving time can vary
• Some test strips don’t detect all chemicals added

Conclusion

After spending some time with this pool shock, we noticed it keeps pool water clear and fights off algae pretty well. Honestly, it outperformed a few other brands we’ve tried, especially if your pool collects a lot of leaves.

But here’s the thing: it doesn’t always dissolve as quickly as we’d like. Sometimes it just sits there, taking its sweet time.

There’s also the bromine factor. Since it might add bromine, your water test results can get a bit tricky if you’re only checking for chlorine.

Good points:

• Keeps water clear
• Controls algae well
• Actually works better than some alternatives

Drawbacks:

• Sometimes slow to dissolve
• Can mess with water tests due to added bromine
