Excellent Value & Quality – Highly Recommend!
Weight: 20.0 Pounds
I recently purchased the PROFELIZ 3-inch chlorine tablets (20 lb) and couldn’t be more impressed. Here are the highlights: 🚚 Fast Shipping Arrived quickly and in perfect condition. 📦 Smart Packaging Every 5 tablets are individually sealed in a sturdy plastic box. No broken pieces, no chlorine dust, and dosing is super convenient. 💧 Strong & Long-Lasting Made with 99% trichloro-s-triazinetrione and 90% available chlorine. Each tablet dissolves slowly and lasts up to a week, even in direct sunlight. Works great in both above-ground and in-ground pools. 👌 Easy to Use Compatible with skimmers, feeders, and floaters. Simple dosing—about one tablet per 6,500 gallons weekly. 💲 Best Price Per Pound This is where PROFELIZ really stands out: PROFELIZ (20 lb): ~$89.99 → about $0.23 per ounce Clorox Pool & Spa XtraBlue (25 lb at Lowe’s): ~$139.00 (or $132.05 with discount) → $0.33–$0.35 per ounce Even though PROFELIZ has 5 lbs less, it’s still 34–36% cheaper per ounce than Clorox. That’s unbeatable value. --- ✅ Final Verdict: Between the fast shipping, secure packaging, high quality, and incredible price, PROFELIZ is hands down one of the best chlorine tablet options out there. I’ll definitely be repurchasing. ... show more

It works well, easy to open, individually packaged 5 per cylinder.Give it a try
Weight: 20.0 Pounds
I've tried several brands, some of them.I prefer over others. Ask compared to other chlorinated tablets.I used to only use three tablets, this one takes 5 tablets to get it perfectly chlorinated. That said, it has stayed consistent with chlorination and cleanliness. The price was good ! Very easy to open the container. The fact that they are individually packaged in cylinders prevents breakage / crumbling , so I have to give it an extra plus for that ... show more

way cheaper
Weight: 20.0 Pounds
These chlorine tablets work exactly as expected and are very effective for pool maintenance. They dissolve slowly and evenly, helping keep the water clear, clean, and free of algae. We’ve had consistent results with stable chlorine levels and noticeably cleaner water. The tablets are easy to use with a floater or dispenser and last a good amount of time without breaking apart too quickly. Overall, this is a reliable and good-quality product that makes routine pool care simple and hassle-free. ... show more

Favorite chlorine tablets, well priced.
Weight: 20.0 Pounds
Excellent pure chlorine 3" tablets. They are not mixed with stabilizer, an indispensable advantage to me. There is no risk of over stabilizing pool water that can render it dangerous requiring it be drained and water replaced. The tablets are well packed in tubes and have never arrived broken.At the 20 pound size, better priced than anything I've seen on Amazon. The bucket top is safely secured and easily opened by depressing a tab on the edge. It arrived quickly and well packaged. This is a repeat order. ... show more

Best Pacgaging and Best Price
Weight: 40.0 Pounds
Some of the best chlorine I've bought. Works well, the price is the best available, and most important, this manufacturer packs the tablets in plastic tubes instead of wrapped in sealed individual bags. This makes useing them a 100x easier. I will definitely be buy these again.

High quality and slower dissolving. Quality stuff.
Weight: 20.0 Pounds
Slow dissolving and doesnt break during shipping due to the individual "coin roll' type plastic cylinders. Each had 5-6 invidual tablets, with NO plastic wrappers to deal with. loading my chrlorinator is simple as popping off the cap and flipping over the opening and they all drop in a perfect stack. These dissolve slower that most other brands, so you can dial in the level easier and not get the huge spike of chlorine. This makes all the difference vs. the store brand. ... show more

Convenient and good
Weight: 20.0 Pounds
These chlorine tablets are great and another bonus of them is that they come individually, packed and stacked in tubes of 5 so they are ready to put into a chlorinator instead of digging through and opening a bunch of separate broken packages like many of the other tablets I have bought.
