Decorative fountains for pond focus on pond beauty. They aerate less than aerating fountains.
Aerating fountains balance between pond beauty and pond aeration
Aerators work exclusively on pond health. No decoration.
We specialize in Kasco and FountainTech floating pond fountains.
We also sell fountain pumps for fountains, ponds, or waterfalls (35-14000 gallons per hour). We sell solar pumps, synchronous and asynchronous fountain pumps, inline and submersible pumps. You will find pond lights here, too, ideal if you want to decorate your pond fountain with lights.
Pond Aeration is needed for fish health. If fish don’t get enough oxygen, they will die. But even if you don’t have fish, without aeration, ponds create stratified layers, and the bottom layer is depleted of oxygen.
In addition, ponds can become shallower over time from a buildup of muck from a lack of oxygen. Plant materials need oxygen to steadily decompose and if new plant life grows at a rate faster than old plants decompose due to a lack of oxygen, that’s bad! Muck accumulates at the bottom of the pond. Gas bubbles arise from the muck. Think Creature from the Black Lagoon eeriness. Think rotten egg smell.
The most common type of aeration and the most obvious is surface aeration. Surface aeration is also the pretty kind, that is, the use of fountains. A pump is placed beneath a float and a fountain head is placed above. Agitation under the water decreases stratification. In addition, the water is forced into the air so that the pond’s water is always being recirculated. Think Bellagio. (Only you probably won’t have air compressors propelling the water farther and higher than your pump can shoot it on its own motor alone.) Surface aeration using pumps can give you a nice display but at the same time get lots of aeration done to enhance pond health.
For very deep ponds (over 8’), bottom aeration is recommended. This is especially true if you have fish. Typically an air compressor is located at the shore and a hose carries the air to a diffuser unit at the bottom of the pond. It is very similar to the air bubbles rising from the bottom of an aquarium. Currently, there are many fairly quiet air compressors available for sale, and they need to be housed to protect from the elements anyway, thus quieting them more.
If you have a deep pond but still want to see a fountain, you can combine the two types of aerators. The fountain for pond would not need to aerate as much and could focus on beauty. This focus allows for a greater range of price as well as dramatic viewpoint.
These are the units written about above, the kind that combine aesthetic pleasure with utility.
These units are workhorses. They are not for beauty. Nope. Get that idea out of your head. They are for pond aeration, period. There will be surface splashing for venting bad gases and allowing oxygen absorption from the air, but these are not fountains. But they are highly efficient from an electrical-use standpoint. A lot of aeration bang for the buck. Again, though, for deep ponds, you still need bottom aeration.
These are something Kasco often recommends as a very under-utilized but super-efficient way to keep water flowing. A motor is mounted horizontally instead of vertically. The water moves not up and down in your pond but across it. You can position them to point in any direction and angle them. Think dock-mounted, for instance. You create a current that can then circle in even a large pond. Since the water is moving, stagnation can be greatly reduced. The current is slow but effective, and the advantage is that small motors can great amounts of water. These can also be mounted at deep levels to mix deep water.
Wind-powered units will either drive a small compressor that pushes air to a diffuser or will be connected to some type of paddle that enters the water and moves as the wind blows. The problem, though, is when the wind is still, nothing is being done.
By far the most common question we get. Can I use solar? Yes. There recently are solar units on the market. The con is they are quite expensive. Please, anyone with experience with these please post!
But if there really is no way to get electricity to your pond, these are available.
Through the years we at Fountain Mountain, Inc. have watched as companies make claims to all kinds of miraculously cheap pond fountains with impossible-to-believe horsepower ratings. Here are some things to ask yourself before buying a cheap pond fountain:
Is the pump UL- or ETL- approved? Or is this fountain pump only approved for use outside the U.S.? If lights with transformers are offered, is the transformer UL-approved?
How difficult is the warranty process? If you must ship back to the manufacturer, is the manufacturer in the U.S., or do you have to ship to another country?
If LED lights are using a controller to program lights, is the housing approved for outdoor use or must it be stored inside a home or barn?
How did the company calculate horsepower? We have seen claims of up to one-half horsepower for a pump that uses only 300 watts of electricity. How is that possible? On what planet does that occur?
How about the size of the nozzle? We have seen pond fountain pumps advertised with 10,000 gallons per hour flow using nozzles that are only 1 1/2" wide in size. These nozzles have holes in them, of course, to create a pattern (the fountain shape). We estimate that in some cases the nozzles are restricting the flow of these pond fountain pumps to about 1,500 gallons per hour. For bigger pumps, bigger nozzles ought to be used.
We have also noticed a fair amount of photo-manipulation in pictures of pond fountains. Sometimes this is understandable. Night photography of lights can be deceptive because of the ways cameras “see” the images at night. But many fountain pics have been greatly manipulated. Try to find sites that give actual non-doctored photos of pond fountains in action. We are a proud distributor of Kasco Fountains and our discount line of Fountain Tech pond fountains for a full range of prices and sizes.
