Awesome product
The best
Dissolve slowly and keep chlorine levels stable. No crumbling or excess residue. Solid option for routine pool maintenance.
Used this to bring down high pH in my pool and it worked quickly. A small amount made a noticeable difference, so careful measuring is important. The liquid is strong and does exactly what it claims, both for balancing water and for light concrete etching. Packaging was secure with no leaks. This is not something to handle casually, but if you know what you're doing, it performs reliably.
