1. In The Swim Pool Shock – 68% Cal-Hypo Granular Sanitizer

In The Swim’s granular shock is a solid, reliable choice for regular pool maintenance. It’s a classic calcium hypochlorite (cal-hypo) shock, and it does the job effectively. I found it easy to use, although pre-dissolving is recommended to avoid staining your pool liner.

• Fast-acting algae control (68% Cal-Hypo)
• Suitable for all pool types
• High chlorine content (65% available chlorine)
• Easy application (pre-dissolving recommended)

Pros:
– Effective
– Affordable
– Widely available

Cons:
– Requires pre-dissolving to prevent staining
– Can be messy to handle

User Feedback Summary: Mostly positive reviews praising its effectiveness and value. Some users mentioned the importance of pre-dissolving.

2. HTH 52035 Swimming Pool Care Shock Advanced

HTH’s 4-in-1 shock promises to tackle multiple pool problems simultaneously. While it didn’t magically solve all my issues (nothing ever really does!), it did noticeably improve water clarity and reduce chlorine odor. The fast-dissolving formula was a plus.

• 4-in-1 formula (kills bacteria & algae, reduces odor & irritation)
• Fast-dissolving
• No CYA added (prevents overstabilization)
• Compatible with all pool types

Pros:
– Convenient multi-functional formula
– Fast-acting
– Doesn’t add CYA

Cons:
– Can be slightly more expensive than other options
– May not be as effective for severe algae blooms

User Feedback Summary: Many users reported significant improvements in water clarity and overall pool condition. Some found it less effective than other options for heavy algae infestations.

3. Clorox® Pool&Spa™ Shock XTRABLUE® Plus

Clorox is a trusted name, and their pool shock lived up to expectations. The 6-in-1 formula is impressive, and the 15-minute swim-ready claim was accurate in my experience. The accompanying app is a nice bonus for those who like extra guidance.

• 6-in-1 formula (kills bacteria and algae, improves filter performance)
• Fast-dissolving (swim-ready in 15 minutes)
• Compatible with all pool surfaces
• Helpful Clorox Pool App

4. Doheny’s Super Pool Shock | Pro-Grade Chlorine Shock

Doheny’s is another strong contender in the granular shock category. The pre-measured bags are incredibly convenient, saving time and effort. It’s powerful stuff; I used it successfully to combat a minor algae problem.

• Fast-acting
• Pro-grade Cal-Hypo (68% calcium hypochlorite, 65% available chlorine)
• Pre-measured 1lb bags
• Effective dosage instructions

Pros:
– Powerful and effective

5. Pool Shock by Aqua Org Plus – 65% Granular Cal

Aqua Org Plus offers a bulk option that’s ideal for those with larger pools or frequent shocking needs. The 50-pound bucket is a significant investment, but the cost per pound is lower. Remember to follow directions carefully.

• 50-pound bucket (cost-effective for large pools)

• Effective for all pool types
• Non-stabilized formula (no CYA)

Pros:

6. Champion 2-Pack Pool Shock, 12.5 Liquid Chlorinator

Champion’s liquid shock is a different approach. It’s convenient, requiring no mixing, but the smaller quantity means more frequent purchases for larger pools. The liquid form is easier on pool surfaces, though.

• Fast-acting sodium hypochlorite formula
• No mixing required
• Doesn’t cloud water or stain
• Cost-effective for smaller pools

Pros:
– Easy to use

• 68% Calcium Hypochlorite
• Simple application (one bag per 10,000 gallons)

Practical Buying Advice:

The best pool shock depends on your pool size, budget, and the severity of any problems. Granular options are generally more cost-effective for larger pools, while liquid shocks might be more convenient for smaller ones. Always test your water regularly to determine the correct dosage and maintain proper chemical balance.

Final Verdict:

There’s no single “best” pool shock. HTH, Clorox and Doheny’s are solid all-around choices. In The Swim provides a good balance of effectiveness and affordability. If you have a large pool, Aqua Org Plus’s bulk option may be ideal. Champion offers a convenient liquid option, while Drytec provides a simple granular solution. Choose the one that best fits your needs and budget.

FAQ:

Q: How often should I shock my pool?
A: Weekly shocking is generally recommended for maintenance. More frequent shocking may be needed after heavy use, storms, or algae blooms.

Q: What is the difference between stabilized and non-stabilized chlorine shock?
A: Stabilized chlorine (with CYA) lasts longer but can lead to overstabilization if not monitored carefully. Non-stabilized chlorine is faster-acting but doesn’t last as long.

Q: What should I do if my pool water is cloudy?
A: Check your water balance and consider shocking your pool. You might also need to clean your filter.

Q: Can I shock my pool with the filter off?
A: No, it’s crucial to run your filter while shocking to distribute the chemicals evenly and prevent damage.

Q: What safety precautions should I take when using pool shock?
A: Wear protective gloves and eyewear. Avoid inhaling the dust or getting it on your skin. Keep children and pets away from the pool while shocking.

Q: What should I do if I accidentally add too much pool shock?
A: Immediately add a pool clarifier and/or run your filter for an extended period. You might need to dilute the water with fresh water, depending on the severity. Consult a pool professional if needed.
