HTH Pool Care Shock Advanced, Swimming Pool Chemical Prevents Bacteria & Algae, Cal Hypo Formula, 1 lb (Pack of 6) : desertcart.in: Toys & Games

Review: Title: Keeps My Pool Crystal Clear and Sparkling! This HTH pool shock works great! It clears up cloudy water fast and keeps the pool looking clean and fresh. Super easy to use — just pour it in at night, and by the next morning the water looks amazing. It dissolves quickly with no residue or strong chlorine smell. I use it weekly, and it really helps keep algae away. Excellent product and great value for regular pool maintenance!
Review: If you are looking for a straightforward way to keep your pool or hot tub inviting, the HTH Shock Ultra is a highly effective choice. This fast-dissolving, 4-in-1 formula is designed to solve 90% of common water problems within 24 hours, making it a staple for regular maintenance. I buy these every couple of months because they work wonders for both in-ground pools and hot tubs. The Cal Hypo-based formula is a standout because it sanitizes without adding cyanuric acid (CYA), which helps you avoid "chlorine lock" and keeps your water chemistry balanced longer. Why this shock treatment is a great choice for your maintenance routine: Restores Clarity Quickly: It effectively kills bacteria and algae while reducing the strong chlorine odor and eye irritation often found in busy pools. Multi-Functional Performance: This treatment not only sanitizes but also provides a visibly brilliant sparkle to the water by removing organic contaminants. Universal Compatibility: It is safe for use in all swimming pool types, including vinyl-lined pools and saltwater systems, providing peace of mind regardless of your setup. Convenient Weekly Use: Designed for easy application, this shock treatment helps you maintain a healthy environment for your family with minimal effort. I haven't had any issues with packages arriving broken or anything leaking out in the box. This 6-pack lasts me about 2 months as I use it for an in-between.

*by S***. on 19 July 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!
