“Our hazard ponds stay clear and healthy for play.”
“Our community is proud of its ponds again.”
“A genuinely chemical-free way to keep pond water healthy.”
“Our pond has never looked better.”
“We have a bee keeping farm east of Calgary and on our farm we have a recreational fish pond that we stock with trout. Our Koenders Windmill has been aerating this pond for over 20 years and it is only recently that we have had to do a little maintenance on it. This 2018 winter was a very long one, it was cold with lots of snow but thanks to our windmill aeration system there was no fish kill. As you can see from the photos we catch some beautiful trout in our water. What a great product!”
A 10-acre farm pond used for irrigation, kept clear by a Koenders 12 ft Windmill and Nature's Pond Conditioner Ultra Concentrate. The before-and-after says it all.
“Our pond is 1.5 million gallons and we have been using Koenders Windmill for 10+ yrs, ULTRA concentrate conditioner and dye for 3-4 years. We recently had a wedding next to our pond.”
“We saw a drastic difference in 7 weeks. Installation went very well. We have been following the schedule you sent on pond conditioner and pond dye. The picture says it all. Couldn’t be happier.”
“Thanks to Koenders aeration and Nature's Pond Conditioner, we are able to enjoy ice fishing again this winter.”
“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. It helps treat the muck that can accumulate over time, and minimizes excessive algae. It is healthier for every critter that interfaces with my pond, besides myself.”
“Nature's Pond Conditioner and our Koenders Windmill Aeration system is a great combination for clean and clear water, which produces healthy and large rainbow trout!”
“We purchased Nature's Pond Conditioner Ultra Concentrate and Dye along with a Koenders Aerator with 4 air stones. We dug the pond in the winter of 2017 and used it for the first time in the summer of 2018. Andrew and Doug were very helpful in creating a maintenance schedule, and the pond stayed a nice blue all summer.”
“In the past we would use dangerous algaecides to keep the algae down, not knowing there was a safer way. We would just keep putting chemicals in our pond, over and over. Then we discovered Nature's Pond 3-step program. We aerate with a Koenders bottom-up windmill and apply Nature's Pond Conditioner and Dye, and the results speak for themselves. Our pond is clean and clear, we are not getting recurring algae, and it has been much less labour intensive and costly than using pond chemicals.”
