Perfect for regular upkeep

This HTH shock is fantastic for regular upkeep. Our pool is around 12,000 gallons, so one bag per week does the trick to prevent algae and keep the water sanitized. The granular form disperses well and doesn't leave any weird film or strong odors like some other products. It's become our go-to for ensuring healthy pool water.

Excellent for keeping our 20,000-gallon pool sanitized and clear.

Didn't clear green water
Kendra C. · 2026-09-13 · Verified purchase
My pool was starting to get a bit cloudy with some green patches, so I tried using this. While it helped a little, it didn't fully clear up the existing algae as effectively as I hoped. It seems better for preventing issues than correcting them.

Clear pool water, easy to use
Gina S. · 2026-10-06 · Verified purchase
This shock treatment truly keeps my pool sparkling. We have an 18,000-gallon inground pool, and a single bag once a week is perfect for maintaining proper sanitization and preventing any algae growth. The granular form dissolves quickly, and it's so much less hassle than liquid shock. I've used other brands before, but this HTH multipack provides consistent results without any fuss.
