EarthTec® Algaecide and Bactericide - 20% copper sulfate pentahydrate

EarthTec® is a highly soluble, self-dispersing copper based algaecide. It is very easy to apply by simply pouring it into your pond. EarthTec evenly distributes through the water body and stays in solution.

Cannot ship to AK, CA, CT, ID, HI, ME, MA, NH, NY, RI, VT, WA or Canada.

Dosage rate 0.33 to 5.43 gallons per acre-foot

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.

It 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.

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.

Figure water volume in gallons. Apply initial dosage of EarthTec (see chart below). Apply maintenance dosage of EarthTec every 14 days.
