Conventional wisdom says that to control blue green algae (BGA), bombard it with copper sulphate.
Conventional wisdom hasn’t met our algaecides.
We found a way to eliminate and control algae with a novel copper-containing solution.
Not only that, but the copper is almost 100% bioactive.
It disperses quickly and completely.
There’s no long-term harmful accumulation of copper.
See results in 24-72 hours.
Eliminate problematic algae completely in 7-10 days.
Sustained control for up to 30 days.
All with a single application.
There’s an Earth Science Laboratories algaecide for each of these sectors: Municipal & Industry, Agriculture and Recreation.

The science, for non-scientists

EarthTec™ works by weakening blue green algae cells. Copper ions stop photosynthesis. The cells begin to die. Cellular material dissolves into the treated water.

Other than the target algae, there is minimal harm to organisms in the water. Even the toxins are biodegraded.

Thanks to advanced chemistry, EarthTec doesn’t settle on the bottom, or float on the surface. It’s rapidly dispersed throughout the water.

These natural processes restore the quality of the water, so it is safe to use.
