Pond Air Pumps – How Different Designs Work Best

I guess to most people, the act of pumping air into a pond doesn’t sound all that complicated.  And in truth it’s not really, but there are a few basics that are good to know if you’re trying to get the best aeration system set up in your pond.

I don’t usually get too hung up on some of the components.  On the airline I do suggest going with self-weighted tubing when dropping the line into the pond simply because it’s easier to manage, sinks on it’s own, and it’s quite durable.  In other words, the benefits outweigh the costs.

Diffusers come in a several kinds of shapes and sizes.  Small ponds use air stones in most cases and these usually work pretty well.  Large pond aeration systems use some kind of rubber membrane to diffuse the air.  It might be in the shape of a tube, or a plate, but for the most part the air output and diffusion is good with either type.

The compressor or pump however is another matter.  This really is the backbone of any good aerator system and it just makes sense to get a really dependable performer to fulfill this important role.

In this article I want to talk about the most common types of pond pumps, how their designed, and where each type is best suited for use.  Certainly each one will work best in a particular setting so I’ll outline those differences in more detail.

Along with that, there’s an “in action” graphic (compliments of Gast Mfg.) to show how easy of these designs works internally.

Pond Muck Reduction And Cleaning

Ponds, simply due to their structure of being a big depression in the ground, are catch-all’s for a lot of things. Unfortunately a lot of this accumulation is organic debris that will eventually break down into a messy muck or sludge.

It’s been said that one of the pond owner’s main goals, if not THE main goal is to slow this process of “filling in” down as much as possible. Once this muck starts to rot and stink, it’s built up to the point where the pond’s natural assimilation processes just aren’t able to keep up with it any longer.

What’s unfortunate is that this mucky compost doesn’t just affect the bottom of the pond. And while it’s true that it serves as a really easy place for weed seeds to get established and rooted, it also releases so many nutrients that algae will often form below and above the water’s surface.
