In The Swim Chlorine-Free Pool Shock - 40 Pound Bucket

Cheaper than going into the swim stores for sure. The shock really does the job. Keeps my pool, nice and blue.

I have been using this chlorine free pool shock since I replaced my vinyl liner four seasons ago. I find that it is more suitable for long term care of my liner and pump / filter assembly and works very well for high-dosing during winter closings. It is very effective at keeping the water crystal clear and keeping algae growth to a minimum. I typically apply it via the skimmer and it dissolves before it is recirculated into the pool. It is suitable for any system that typically uses chlorine based shock / tablets.

It’s exactly what’s in the box and works!

Easy open dosage packages. Great price. Dissolved quickly and did exactly what I expected.

Great for price point

Have used this shock for years and does the job well. we have a 15x30 saltwater pool. I use one bag weekly as maintanace during regular use. I use 2 bags for after heavy use like a party or suspected algae contamination or outbreak.

I love using this in the Summer for a little boost of clean to my above ground pool when a straight bottled chlorine shock isn't needed yet. Keeps it clean, fresh, and clearer but not a shock for algae, bacterial or viral accidents, or when chloramines are too high.

A lot cheaper then pool store, and same chemical.
