Review: Crystal Clear Water with a Reliable 4-in-1 Treatment - 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.

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.
