### ⭐⭐⭐⭐⭐ Need these for your pool/hot tub
*by S***. on July 19, 2025*

The HTH 52036R Pool Care Shock Advanced has become my go-to solution for keeping our hot tub water clean, clear, and safe all year long. This 6-pack is a fantastic value, and the calcium hypochlorite (cal-hypo) formula really does the job. Fast-Acting Shock Treatment: Within just a few hours of applying, the water goes from cloudy or dull to sparkling clean. It clears up algae and cloudy water impressively fast. Kills Bacteria & Prevents Algae: I’ve had issues with algae growth in the past, especially during hot, humid weeks. This shock keeps that completely under control. It also gives peace of mind that bacteria are being eliminated regularly. Each packet is pre-measured and dissolves quickly without leaving residue. No complicated mixing or measuring—just pour directly into the pool. The HTH Shock Advanced is a powerful and convenient way to maintain a clean and healthy pool. It restores clarity, controls algae and bacteria, and is very user-friendly. A pool care essential—I always keep a box on hand!

### ⭐⭐⭐⭐⭐ The only kind we purchase!
*by T***I on September 17, 2025*

This is our first year having a pool. After trying several different shocks we settled on HTH Ultra Pool Shock.The product dissolves quickly and doesn’t leave behind any residue or cloudy water like some cheaper shock treatments I’ve tried in the past. Within a few hours of application, the water looks noticeably clearer, and it does a great job of eliminating that faint “chlorine smell” and any algae or bacteria growth.I also appreciate that the dosing instructions are straightforward, so there’s no guessing game when treating different pool sizes. One packet is usually enough to restore balance after a heavy swim day, rainstorm, or when the water just starts to look a little dull. It gives me peace of mind knowing that my family is swimming in clean, well-sanitized water.Overall, HTH Ultra Pool Shock is reliable, effective, and worth the price for the results you get. If you want a hassle-free way to maintain crystal-clear water, I highly recommend it.

### ⭐⭐⭐⭐⭐ Read the instructions and get within the spec ranges first
*by R***E on August 13, 2025*

This stuff works! makes life easy and water clear and clean. I don't smell anything, but my pool is outdoor and not indoor so there's that. I say this is quality stuff for sure.Granted i still needed some clorox for pool and spa and some muriatic acid and some baking soda to level things out. But after things are within range, and this is dissolved, separately, just dump it right into the filter stream and let it go.After 4 hr for my little 800 gal pool, it's clear and purrfect to play in!
