Review: Great Price and Excellent Customer Service! - We ordered Pool Shock by Pyrock Chemical. The price was right and the best part was it’s delivered right to the door. The delivery date was perfect for our needs. Unfortunately on the day that we expected the delivery, we received a notification from desertcart that the delivery was delayed.

The seller soon responded and said the shipment was apparently lost. They offered a refund or replacement. I requested a replacement. Once again the seller promptly replied. We received the replacement Pool Shock the next day. Great price, and excellent customer service!

### ⭐⭐⭐⭐⭐ Fast delivery and great price

This shock does a great job for my large above ground pool! Very pleased and fast delivery.

### ⭐ DO NOT BUY
*by R***Y on November 10, 2025*

DO NOT BUY THIS STUFF, PLEASE LISTEN TO THE NEGATIVE REVIEWS. I do not leave many reviews but i had to for this. You get what you pay for. First off it is like a solid block and you have to scrape it with a metal garden shovel to break it up. There are pieces of black plastic throughout. When you use it, this stuff is worthless. It clouds the water, it does not dissolve, it leaves little white particles floating on the surface of the pool and most of it sinks to the bottom, which in turn clogs up the filter. The worst part is it does not work!!! I used 3 times the recommended amount and the chlorine test still showed under 1 PPM. I do not know what is in this but it does not do anything. Water stays green tint until I use a different product. A one pound bag of shock of a different brand or a jug of liquid chlorine does way more than 6 pounds of this stuff. I have never felt more ripped off by any item i have bought. Amazon should stop selling this stuff, it is a rip off.
