Description
Fast algae knockdown with liquid placement control
When you need quick cleanup without switching to a granular treatment, Cutrine Plus gives you the control of a liquid concentrate with the hard-water stability of a chelated copper formula. It is especially useful for planktonic blooms, floating or suspended filamentous growth, and other algae problems where even surface coverage matters. For deeper bottom-growth zones, a granular program may still be the better fit.

Why Choose a Liquid Chelated Copper Algaecide?
- Rapid visual response: The label and product sheet support visible algae reduction in as little as 24 to 48 hours.
- Better placement control: Liquid application makes it easier to coat surface mats and treat water-column problems with common spray equipment.
- Stronger buying confidence: EPA registration, labeled post-treatment water uses, and broad algae fit help reduce guesswork before purchase.
