We talk a lot about pond aeration and why it’s so important for almost any size of pond. Normally in our discussions we focus mostly on sub-surface aeration, simply because it does so much for the entire pond. But it should be noted that there are many kinds of aerators for ponds and one of the most useful is actually called a circulator.
A pond circulator isn’t really anything fancy. It includes a motor, usually something like a 1/2 HP up to maybe a 1 HP, which is attached to a specially designed propeller and a prop guard. There are several other options that can be used with a circulator. A floatation device is very useful for working near the top of the pond, and there are dock mounts, and timer accessories which make this a powerful, all season too for pond management.
In the summer months, circulators work great to keep debris from forming in really stagnant waters, and they can work in very shallow conditions (down to about 2 feet or so) and then can increase oxygenation in back coves and hard to reach areas of some ponds.
In the winter, they are the number one tool for ice control around docks and boat ramps, and when used with a thermostatic timer, they will only run when the water begins to freeze up, then turn off when ice isn’t a threat any longer.
We’re finding that we’re using circulators more and more, either on their own, or in combination with other aeration systems and the results have been terrific. So if you find that you’re fighting stagnation, debris accumulation, or have had problems with ice damage in the past, take a look at one of these circulators. It might be just the ticket to a more trouble free pond.
Note: We usually size these by matching HP to pond surface area. The 1/2 HP works great in pond sup to 1/2 acre, and the 1HP works great in ponds up to about 1 acre in size.
