Keeping your pond free of weeds is essential for the health and beauty of your pond. Weeds can clog filters, reduce oxygen levels, and compete with beneficial plants and animals.

Healthy Ponds carries a line of algaecides and herbicides that effectively control pond weeds and algae. These chemicals are not to be confused with Healthy Ponds’s all-natural products. These Healthy Ponds products are not classified as algaecides.

Our pond chemical products provide effective solutions for killing algae and aquatic weeds. They are carefully selected for optimal compatibility with our all-natural products.

What Causes Pond Algae Growth?

Several factors can contribute to the growth of pond algae, including:

  • Improper aeration
  • Improper filtration
  • Too many fish
  • Too much sludge & debris
  • Too much sunlight



These treatments simply can kill or mitigate algae, often utilizing copper sulfate or chelated copper. Copper is effective because it basically attaches itself to the algae in your pond and prevents photosynthesis, which causes the algae to die.

It is crucial to use the right pond chemicals to help kill unwanted guests in the pond, and provide a safe and pleasant habitat for your marine life friends.


While certain types of pond bacteria can be harmful to your water, there are all-natural beneficial bacteria that can reduce many common problems such as sludge buildup and the accumulation of floating green organic matter. Our all-natural products are safe for fish, wildlife, livestock, pets and people.

We have all-natural products to prevent algae growth before it becomes a real problem.
