EarthTec® is a proven, reliable and environmentally responsible solution to recurring algae blooms that can create a real problem in the maintenance of  lakes, ponds and fountains.

EarthTec®, an algicide and bactericide, is designed for use in lakes, ponds, fountains and other water systems. 

Earthtec is a liquid copper water treatment product registered as an algicide and bactericide with the US EPA and Certified to NSF/ANSI Standard 60 as a drinking water additive.

The active ingredient in EarthTec® is a biologically active form of copper ion (Cu++). Unlike other copper algicides available today, the copper in EarthTec® is already fully dissolved, and more importantly, the release of its active ingredient is controlled by biological demand (such as an algae bloom) instead of by water conditions.

This allows you to treat your pond or fountain prior to an ugly outbreak of algae. The copper will not precipitate out of solution, but will remain fully dissolved indefinitely, thereby insuring long-term algae control without overtreatment.

Save Time and Labor

EarthTec® will rapidly and evenly self-disperse throughout the body of water to which it is applied — without mixing or agitation, minimizing equipment and labor costs. Regardless of dilution rate, the active ingredient in EarthTec® will always be uniformly distributed.

Lake and pond water may be used immediately following treatment for irrigation without harm to plants or grass. EarthTec® may also be used in fish-bearing ponds at prescribed application rates.

EarthTec® Dosage Rates

Figure water volume in gallons (length x width x average depth x 7.5). Apply initial dosage of EarthTec® every 14 days until visible algae disappear. Then apply maintenance dosage of EarthTec® every 14 days. See charts below.
