The only kind we purchase!
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 doesnโt leave behind any residue or cloudy water like some cheaper shock treatments Iโve 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 โchlorine smellโ and any algae or bacteria growth. I also appreciate that the dosing instructions are straightforward, so thereโs 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.

Great pool shock!
I use the shock All Summer Long in my pool. It does exactly what it says it's going to do. It arrived without any types of spills or tears in the packaging. This is my go to shock for my pool as it clears it up as soon as I open it and keeps my pool nice and clean throughout the summer season.

Keeps spa clear
Although it is not recommended we use this in our hot tub spa. Just adjust the amount to allow for the smaller pool. Like the product keeps the water clear. Once the pH was balanced this product seems to maintain everything well.

I had this stubborn black mold looking stuff in the rubber seal around my washing machine from previous owners. I had tried everything!! Bleach, vinegar/baking soda, intense scrubbing, endless cleaning cycles, the tablets made for cleaning washing machines, etc. Nothing worked. This stuff did. Obviously be careful though, it's very potent.
