Why You’ll Want Leslie's Power Powder Plus 73 Pool Shock in Your Pool Kit Now

Dealing with cloudy water or stubborn algae? One bag of Leslie's Power Powder Plus 73 Pool Shock can turn things around fast. This high-strength chlorine treatment works quickly and packs serious sanitizing power. It’s one of the top choices for pool owners who want strong results without complicated steps.

At around $89.99 for a 12-pack of 1-pound bags, it delivers real value. Each bag is easy to use and effective. You’re getting 73 calcium hypochlorite with each dose—no stabilizer, no guesswork.

Let’s walk through why this product belongs in every pool owner's kit.

Leslie's Power Powder Plus 73 Pool Shock stands out for a few key reasons. First, strength. It contains high-strength chlorine shock with 73% calcium hypochlorite. That means it works fast to clean up water issues.

It's a fast-dissolving pool shock, so it won’t leave clumps or gritty residue behind. It clears the water while helping you manage calcium levels.

This is a non-stabilized chlorine shock, which matters if you already have enough stabilizer in your pool. Too much stabilizer can weaken chlorine and leave your pool exposed to algae and bacteria.

Each package includes twelve 1-pound bags. That makes it easier to store and use only what you need. No scooping. No waste.

This product uses chlorine granules for pool sanitation. When added to your water, it releases chlorine quickly. That spike in chlorine breaks down chloramines and kills harmful stuff like algae, bacteria, and viruses.

This treatment works harder than basic liquid bleach or slow-dissolving tablets. With 73% available chlorine, it gives you more cleaning power per pound.

For maintenance, it works well on a weekly schedule. During hot months or heavy pool use, it helps keep things clean and balanced.

A non-stabilized chlorine shock like this one doesn't add cyanuric acid. That's important if you're already using stabilized chlorine tablets.

Using too much stabilizer over time can lead to chlorine lock. That’s when chlorine levels look fine but don’t actually work. This shock keeps things in check.

It’s ideal for treating problems fast and for weekly use when you don’t want to mess with your stabilizer levels.

Follow these steps to get the best results:

• Test your water first
• Add 1 pound per 10,000 gallons for regular maintenance
• Use 2-3 pounds per 10,000 gallons for algae or cloudy water
• Dissolve it in a bucket of water (never add water to the powder)
• Pour around the pool with the pump running
• Let the pump run for at least 8 hours

Apply it at night. Sunlight breaks down chlorine quickly, so nighttime use helps you get the most out of each treatment.

Always test your chlorine levels the next day. Wait until levels are below 4 ppm before letting anyone swim.

Use it weekly during swim season. It helps prevent cloudy water and keeps algae from taking over. Use a higher dose after:

• Heavy use or pool parties
• Rainstorms
• Seeing algae or murky water
• Smelling strong chlorine (this means chloramines are building up)

During pool opening and closing, use a double dose to clean things out and prep the water.

This is a strong pool shock for algae and bacteria. Use it when green, yellow, or black algae show up.

• For green algae: Use 1 pound per 10,000 gallons
• For yellow: Double the dose
• For black: Triple the dose and brush hard

Run the pump and clean the filters afterward. Follow up with algaecide if needed.

If your pool water still looks off after shocking, check for:

• Filter problems
• pH levels outside 7.2–7.6
• Very high calcium (over 400 ppm)
• Not enough shock applied

You might need to reapply or add a clarifier if tiny particles stay suspended in the water.

This product comes in a 12-pack of 1-pound bags. That’s enough for weekly use over a three-month swim season in a 15,000-gallon pool.

Use exact amounts. Don’t guess. Store the bags in a cool, dry place. Avoid moisture and sunlight.

Shelf life is around 1–2 years if stored right. Keep bags sealed until use to avoid losing strength.

When you shock your pool, test your water before and after. Focus on:

• pH: Keep it between 7.2 and 7.6
• Alkalinity: 80–120 ppm
• Calcium hardness: 200–400 ppm
• Stabilizer: Under 50 ppm

High heat or heavy pool use can burn through chlorine quickly. In those cases, adjust the dosage.

Always check chlorine levels the day after shocking. Adjust with tablets or floaters as needed to maintain proper sanitation between shocks.

This product is strong, so handle it carefully. Always:

• Wear gloves and goggles
• Avoid breathing in dust
• Never mix with other chemicals
• Keep it away from pets and kids
• Store in a sealed, labeled container

Wait 12–24 hours before swimming. Recheck chlorine levels to be safe.

Absolutely. Leslie's Power Powder Plus 73 Pool Shock brings solid cleaning power and convenience. It works fast, dissolves cleanly, and helps you stay ahead of algae, bacteria, and cloudy water.
