Welcome to Koenders Water Solutions' official website. 

From the rural community to the big city, we are one of the leading manufacturers of natural, environmentally safe pond care and cleaning products in North America. 

Bottom-Up Aeration

In 1988 we innovated the windmill for farmers' dugouts. Then we added electric and solar aeration products.

Today our aeration systems are used on farms, ranches, golf courses, public ponds, and municipal wastewater lagoons around the world.

We have aeration systems for any size pond, from small koi fish ponds to recreational lakes.

Nature’s Pond Conditioner - Powered by Nature

Algae blooms and unwanted aquatic plant growth can quickly overrun a pond or dugout.

Herbicides are a toxic quick fix and can lead to costly dredging to remove decaying algae and aquatic plant matter that sinks to the bottom.

Nature’s Pond Conditioner is an environmentally friendly blend of beneficial bacteria and enzymes that naturally treats the source of algae growth: nutrients like phosphates and nitrates.

Our pond treatment products are safe for people, fish, pets, and the planet.

Pond Care Program

Bottom-up aeration, Nature’s Pond Conditioner, and removing unwanted aquatic plants with our Cutter ‘N’ Rake, form the core of our Pond Care Program: Renew, Revive, Remove.

We can customize a Pond Care Program for any type and size of water source.

Your journey to preserve and protect our freshwater resources starts here!

Our Customer Stories

“The results are exceptional. The water is so clear you can see the fish. Nature’s Pond has enhanced the beauty of this natural ecosystem, and made us very satisfied pond owners.”

Fraser Wilson, Ontario

“Since we started using Nature's Pond Conditioner in conjunction with the Koenders Aeration Windmill our pond looks great! We haven’t had to do anything else to it. Nature's Pond Conditioner is also very easy to apply.”

John Pagano, New York

Even the bears love our pond

"I wish I heard about Koenders a long time ago. I initially started with chemicals but there was no end to 'feeding the beast' because of the amount of chemicals that needed to be put in as it wasn't actually treating the water issue, it's just killing off the resulting algae.

Koenders products have made a huge difference in the appearance and health of our pond. Thanks for all your help.

We use Nature's Pond Conditioner Ultra Concentrate and Koenders HD250 Electric Aerator."

Dan, Novato, California

Leaving more to the land than as we came to it

"Your product was made of great quality. I was not disappointed when my high school best friend Rito and I got to erect this windmill together in our retirement. We had no problems with parts and quality-very, very nice including the bag of spare parts. I would recommend the Nature’s Pond Care products as a healthy choice to enhance the benefits and bring out the full potential of a pond and its contribution to the quality of life on our properties. It helps treat the muck that can accumulate over time, and minimizes excessive algae effects. It is healthier for every critter that interfaces with my pond, besides myself."

Jim, Wisconsin
