Cleaning up the water, not adding to the problem

Cleaning up the water, not adding to the problem

At Grand Lake St. Marys in Ohio, the water had turned against the people who lived on it. Uncontrolled blue-green algae, the kind that produces a toxin called microcystin, had bloomed across parts of the lake and its lagoons.

The trial

The FFT Nutrient Enhancement Agent was trialed there to help bring the bloom back under control. What stands out is the restraint. The product was applied at very low doses, measured in parts per million, and the trial tracked the water over weeks to watch the trend.

The principle

One rule guided the whole effort, and it's worth stealing for your own home: never treat a problem that is harming the environment by harming it further. The right dose is the one that helps the water recover without trading one problem for another. Too heavy a hand, and you've just swapped a green problem for a chemical one.

Why we're telling you this

You are not dosing a lake. But every capful of Kan Klean eventually leaves your house. It runs into a drain, through a septic field or a greywater system, and back toward the same water everyone shares. That is exactly why we built Kan Klean to be powerful enough to handle the mess and measured enough to be safe on the way out. The lake trials and the bottle under your sink come from the same belief: clean should not cost the water anything.
