For many years, pond algae problems have been treated with a copper based pond algaecide and while those have been effective they often come with some unwanted side effects.

Most notably many copper products will kill algae but they also sink to the bottom of the pond where copper levels can accumulate and get concentrated. Copper is toxic to algae but it's also detrimental to beneficial bacteria which is important to maintain for keeping the pond bottom clean.

What's been needed for a long time is a product that won't sink quickly to the bottom and one that will stay suspended for a longer period of time.

Fortunately pond owners now have a choice in a copper based algaecide that does just that, and it's called EarthTec. EarthTec will stay active and suspended in the water column indefinately and it only get's used up based on biological demand...meaning it's in place and activated whenever it comes in contact with algae.

What's great about this process is that it allows a pond owner to use a much lower copper concentration in their pond to control algae. And because EarthTec remains suspended, you will generally need to treat less often and in a lower dosage than other algaecides.

Because of these benefits, EarthTec is the only algaecide of it's kind that we recommend and use, and it's replacing chemicals like copper sulphate, Cutrine, and White Cap for many pond owners looking for a safer, more eco-friendly way to control their algae problems in a larger pond.

We suggest using EarthTec in ponds of 50,000 gallons or more.

How to apply:

Simply pour in the recommended amount of EarthTec. Dosage charts can be found below.

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.

Precautions for fish:

As with any algaecide (including Algae-Off Algaecicde) or chemical that can kill algae and vegitation quickly, care should be given when applying this product in a pond with fish. It is best to use maximum aeration during the treatment phase to ensure adequate amounts of dissolved oxygen are maintained in the pond. If the algae bloom is heavy and widespread, it may be desirable to use a one time treatment of copper sulphate in which you can spot treat sections of the algae over a period of time. Doing this will reduce the chances of oxygen depletion in the pond and once cleared, clarity can be maintained with EarthTec.

Under no circumstances should a copper based algaecide be used in a pond with trout or other species sensitive to copper.

Our suggestions for dosing:

In our use of the product we like to follow the recommended initial dosing instructions as suggested below. For follow up treatments, you can use the 14 day cycle as outlined below, or routinely test the amount of copper concentration in your pond every two weeks. The goal is to maintain the copper level at or around 0.06 ppm, or the lowest level of possible for effective algae control. The dosage rate may vary from pond to pond as well as the species of algae you are trying to treat.

To treat be sure to 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 or test to maintain recommended copper concentration in the water. See charts below.
