Best Algae Killer for Ponds - Algaecide Treatment

The Algae Control Package is a professional grade algaecide and catalyst for enhanced algae control in ponds. It is most effective for controlling filamentous algae and chara algae.

  • Accelerates algae break down
  • Controls Algae better than using an algaecide alone
  • Great choice for pond owners struggling with algae problems
  • All 3 products can be tank mixed together for a single treatment

Contains 1 gallon of Cutrine Plus liquid algaecide, 1 gallon of Pondzilla Pro treatment accelerator, and 32 ounce PlexMate Surfactant. Tank mixing these three treatments together provides faster, and more effective solution for killing string algae and chara. The Algae Control Treatment Pack is designed for natural fish ponds and farm ponds.

Treats 8,600 square feet

Treatment instructions for Algae Control for Ponds: 

To treat 2,000 square foot surface area mix 32 oz Cutrine Plus, 32 oz Pondzilla Pro, 4 oz Surfactant, and 2 gal water. Mix in a tank or backpack sprayer. Spray algae directly. 3 gallon Sprayer sold here

FOR BEST RESULTS treat early on a sunny day.  Treat only half of the pond surface at a time, waiting 10 to 14 days before treating second half, unless there is adequate aeration installed.

What happens to algae after the algaecide application?

Begin to notice results within 24-48 hours after application of algaecide mixture. As string algae and/or chara die, it floats to the surface in large mats. It turns yellow/brown as its dying. Within 10 days the mats will lose buoyancy and drop to the bottom where it decomposes.

Pond algae control - algaecide

How long will this treatment control algae?

Both string algae and chara muskgrass have no root systems. Algae blooms occur because nutrients are available in the water. To limit future growth, treat water with pond dye to block sunlight from reaching the pond bottom. Natural bacteria treatments like Muck Remover and Pond Cleanse reduce nutrients and bottom muck that feed algae.

Natural Ways to Control Pond Algae Blooms

Algae blooms are often caused by water quality that is out of balance. Excess nitrogen and phosphorus provide the fuel that algae need to grow and multiply. When extra nutrients are available in the water, algae blooms occur. Sunlight exposure and alkalinity (carbonate hardness) of the water contribute to algae blooms. 

Natural beneficial bacteria and phosphate binders can be used to help control pond algae by limiting the growing conditions.

What causes algae to grow in ponds

Algae blooms can be harmful to aquatic life. Some particular species of algae and cyanobacteria produce toxins. Common algae blooms can be harmful in subtle ways. 

During the day algae produces more oxygen than it consumes through photosynthesis and releases that oxygen into the water. Once the sun sets and photosynthesis stops, algae still uses oxygen but are not producing it. The result can be dangerously low oxygen levels which can result in fish kills. 

Severe algae blooms are also harmful to native plants in water that provide habitat for fish and other aquatic life. The floating algae actually shade the pond bottom and prevent growth of healthy vegetation.  

How does Pondzilla help control pond algae?

Pondzilla is a catalyst for algae treatments that provides multiple benefits. It improves algaecide penetration into the algae to accelerate the chemical reactions that kill algae in a pond environment. Particularly in hard water (high alkalinity/carbonate hardness) it is critical to improve the penetration of copper based algaecides into the algae. 

Pondzilla helps break down dead algae and fixes the nutrients that can be released back into the pond water. A blend of enzymes, fungi, stimulants, and bacteria break down the algae on a cellular level completing the pond algae control cycle. Pondzilla is the ultimate companion to the copper-based Cutrine Plus Liquid Algaecide.

Do not use Pond Algae Control Treatment Pack in ponds with koi, goldfish, or trout unless carbonate hardness is over 50 ppm.  Agricultural lime can be used to raise the carbonate hardness above 50 ppm for safe treatment.  

No water use restrictions- water can be used after treatment for livestock, swimming, fishing or irrigation.
