Advanced Copper Chelate Technology
What makes Applied Biochemists Swimtrine Plus stand out is its chelated copper formulation. This advanced chemistry keeps the copper active and evenly distributed throughout the water, preventing it from staining pool surfaces or precipitating out due to pH or alkalinity changes.
This ensures:
-
Longer-lasting effectiveness per dose.
-
No staining on vinyl, fiberglass, or plaster surfaces.
-
Stable performance under varying water conditions.
You’ll enjoy extended algae protection without the common drawbacks of traditional copper-based products.
Works on All Algae Types
Swimtrine Plus is powerful enough to handle the full spectrum of common pool algae, including resistant varieties that chlorine alone can’t eliminate.
Targets and Controls:
-
Green algae – the most common bloom that clouds and discolors water.
-
Mustard (yellow) algae – forms clingy deposits on pool walls and steps.
-
Black algae – stubborn growths with protective layers resistant to brushing.
Regular use keeps your water clean, your walls spotless, and your filtration system free from organic buildup.
Safe and Compatible with All Pool Systems
Swimtrine Plus integrates seamlessly with any existing sanitizing program, including chlorine, bromine, ozone, and saltwater systems. Its non-foaming formula makes it safe for in-ground, above-ground, plaster, vinyl, and fiberglass pools.
It also complements regular sanitizers, meaning you can continue normal chlorination while eliminating algae at the source.
