Professional Copper-Based Algae Control for Lakes and Large Ponds

Take control of surface and suspended algae in lakes and large ponds with EarthTec Liquid Algaecide, a highly soluble, self-dispersing copper-based formula designed for professional-grade algae management. This powerful liquid algaecide provides effective control while remaining in solution to prevent algae regrowth until the product is naturally depleted.

Engineered for ease of application in large water bodies, EarthTec self-disperses throughout the water column. Simply pour the product into the water, and it distributes itself to target algae where it grows.

Two Sizes Available

ETEC1 – 1 Gallon – Ideal for smaller lakes, large ponds, or spot treatments. Easy to handle and store for regular treatment schedules.

ETEC25 – 2.5 Gallons – Professional-grade quantity for larger lakes or commercial applications. Better value for large-scale treatments. Includes additional $40 hazmat fee.

Frequently Asked Questions

Which size should I choose?

Choose 1 gallon (ETEC1) for smaller lakes or spot treatments. The 2.5 gallon (ETEC25) is better for larger lakes or commercial applications. Note that ETEC25 includes an additional $40 hazmat fee.

How do I apply this product?

Simply pour the product into the water. For ponds over 3 acres or to speed distribution, apply to several locations around the water body. The self-dispersing formula spreads on its own.

Can I treat my entire pond at once?

No, do not treat more than 1/2 of a lake or pond at a time. Treating the entire water body can cause oxygen depletion as algae dies and decomposes.

Is this safe for fish?

Not for use in waters containing trout, koi, or other fish susceptible to copper. Verify fish species compatibility before treatment.

How much product do I need?

Dosage rate ranges from 0.33 to 5.43 gallons per acre-foot depending on algae type, severity, and water conditions. Follow label directions for proper dosing.

What types of algae does this control?

EarthTec is effective against both surface algae (mats and scums) and suspended algae (green water).

Why can't this ship to certain states?

Regulatory restrictions in AK, CA, CT, ID, HI, ME, MA, NH, NY, RI, VT, WA, and Canada prohibit shipment of this product to those locations.

Can I use this in my koi pond?

No, this product is not for use in waters containing koi or other fish susceptible to copper. Use alternative algae control methods for koi ponds.
