3rd party study confirms that Koenders windmills have the best performance ratings in the industry!Read more About it
You want clean and healthy water and it matters to you how you achieve it. Oxygenation is a natural and organic way of breathing life your pond through tiny bubbles created by aerators. Oxygen is the ingredient that enzymes and bacteria rely upon for energy. The more they get, the more they consume the excess nutrients, roundoff and pond muck in your pond, leaving your pond clean and algae at bay.
Building on the legendary reputation and award winning Koenders EL2, the new HD 250 is the next generation of aerators that produces 2 to 3 times more air than the EL2. If your pond is up to one acre in size and as deep as 30ft the HD 250 is your best choice.
The HD 250 is a high performance, low energy aerator designed to provide pond owners with the best performance and reliability in its price category.

"Our pond brings a great deal of pleasure to me, thus I want to keep it algae and muck free especially in the hot summer months where pond water issues area more predominant. This year we had a very hot summer, extreme temperatures that got up into the high 80’s, low 90’s and with the use of Koender’s Nature’s Pond Conditioner and aeration windmill I was able to keep my pond algae and muck free. My goal has always been to prevent pond water issues from occurring as opposed to waiting until there is an issue."
