Pond Aeration Systems - Basics of Selecting and Installing

!±8± Pond Aeration Systems - Basics of Selecting and Installing

When looking for a solution to managing water quality, or simply for aesthetic enhancement, there are three basic types of pond and lake aerators to consider; surface spray aerators, air diffused systems and horizontal aspirators or mixers. Each type has unique differences and efficiencies which can be utilized in many different ways to achieve maximum benefit. Below are some basic guidelines to take into account when selecting and installing an aeration system.

Selecting an Aeration System: The size, shape and depth of a pond should dictate the type of aeration system, or combination of systems to be used; keep in mind when water quality management is an objective, recommended sizing is 2HP per surface acre.

Surface Spray (Floating) Systems: Ponds less than 15 ft deep, or wherever fountain spray aesthetics are desired.

Diffused Aeration Systems: Ponds 15 ft and greater in depth, and when no surface spray is desired. (Note: Efficiency is lost when used in ponds less than 15 ft, but can be remedied with additional diffuser manifolds placed throughout the pond. These systems are not recommended for ponds less than 8 ft.)

Mixers and Aspirators: In ponds less than 9 ft deep where lateral movement is dictated, or no surface spray is desired.

Electrical Requirements: In order to operate the systems efficiently, and without nuisance tripping, it will be necessary to know if sufficient power is available, how close it is to the source, and if there are other electrical requirements that may be utilizing the same source, ie. irrigation, lighting, etc. It's also important to follow both local and national electrical codes during installation, which will often require burying/trenching wire in conduit from the power source to the aerators power control center, and from the PCC out to the ponds edge.

Having operational electricity is necessary before flotation and start-up of any aeration system, for security and mechanical considerations, and may become a scheduling consideration that could need attention. A certified electrician may also be required during installation.

System Installation: There are two ways of securing most units into position, anchoring (to the pond bottom), and mooring (to the pond edges, either above or beneath the surface.) Methods of securing and quality of materials used can affect security, ease of service, and safety, and should be included in the planning process. Tools and materials required can include: a shovel (to bury/trench cable,) conduit, stainless steel cable or nylon rope, cinder blocks and a boat (when anchoring,) and rebar or duckbill anchors (when mooring.) Diffused Air Systems do not require anchoring or mooring, but a boat is often required during installation.

Intensive landscaping around the pond such as retaining walls, waterfalls, and planting beds could affect the installation process, in addition to future available access for service or maintenance. Further coordination may be needed between the aeration installer and landscape and/or irrigation contractor in these instances as well.

Buying or Building Your Own Water Fountain

Things to Consider

A great deal about fountains has changed over the last decade. Now there are really high class ones made of copper, bronze, concrete, and stone, and some fairly nice ones made of resin and fiberglass. There are several things to consider, though. As a pump wholesaler, I speak with fountain owners all the time and also look at lots of samples of fountains at trade shows and in magazines. Before purchasing a fountain, there are quite a few questions to ask. What looks good in a store might not look good at your home or business. Or it might look good for the first month or year but then you'll get tired of it. Fountains are usually around for a long time; in fact, concrete and stone ones last centuries and are hard to remove once they're installed. Here are things to consider.

Bronze Fountains

These are at the high end of fountains, and can retail for ten to twenty thousand dollars. They are plain classy. But will one of these fit in where you want to put it? Do you have the right yard or business or location for such a classic kind of display? Also, do you like the aging process (the verdigris patina) that bronze undergoes. Can you afford one of these? If you answered yes to these questions, a bronze fountain might be right for you. It will last your lifetime, your kids' lifetimes, their kids' lifetimes, etc. And they are durable enough to be moved from house to house.

Copper Fountains

Like bronze fountains, these too tend to be classy, especially the name brand ones like Water Wonders, which mix copper with glass and slate. These make especially nice wall fountains. We have been selling Water Wonders fountains for several years at Fountain Mountain. There are certain things to think about, though. Are you locating the fountain in a room with good acoustics? Some rooms make the pump noise really echo, especially small rooms with walls that are close together. Do you know someone or can you hire an electrician to hide the cord in the wall? These fountains are a bit too expensive to buy if you're going to let the cord run outside the wall for everyone to see. Finally, it is a good idea to go listen to them run at a store before purchasing. Some of them make little water noise and some make a lot. To increase water sound you might have to turn up the pump to the point of there being slight splash. But if you are careful and go to a store with Water Wonders or other copper fountains on display before purchasing, and are happy with what you see and hear, these are great fountains.

Concrete Fountains

These still provide the most bang for the buck, primarily because concrete is so inexpensive. In fact, a huge part of the cost of concrete fountains is in transporting them to stores for sale and in the labor of painting them. The concrete itself is the least expensive part of the fountains' manufacture. There are some differences in how they are made, though. Some companies, like Brandelli's, use a "light" mix: their fountains are not nearly as heavy as those produced by, say, Avila's. Also, some companies like Brandelli's, use a stain over concrete, whereas others, like Avila's or Lomelli's, use paints (usually more than one at a time) or stains. Also, most concrete companies (though not all) reinforce their fountains with steel. This makes them strong but also means the concrete must be sealed. If not painted (as most fountains from Mexico are not), then they do need to have a clear sealant put on them. Otherwise the water will seep through to the steel, which will rust. Eventually, the fountain is likely to crack. One final word of advice on concrete, beware of "cute." Cute fountains (mama dogs with baby dogs, boys peeing) sometimes don't look so cute over time. Ask yourself if you'll still think the fountain is cute years later. Remember, concrete fountains can last hundreds of years. And they are difficult to move so pick something that will stay put. The traditional Italian 3-tier fountain is always a safe bet.

Resin and Fiberglass Fountains

The quality of these has gotten a lot better, and they have the clear advantage of being more easily handled than concrete ones. Some do look like concrete and stone, though they tend to look much more realistic at first glance than they do after a week has passed. Then it is pretty clear that they are faux. These are also a lot easier on employees who work in tores, as they don't have to worry as much about their backs. We would sell these at our store but just don't like their looks as well as the real thing.

Stone Fountains

These look incredibly good or mediocre. The handcrafted stone fountains out of Mexico and many of the large ones out of China are beautiful. But there are also mass-produced stone fountains, which use crushed stone mixed with resin. These just don't look like real stone to us even though they are.

Making Your Own Water Fountain

There are lots of ways to make your own fountains. The easiest way, perhaps, is to place a pump in a small tub or on some liner. Then place a wire or plastic grate on top of the tub or the liner, and layer pebbles, rocks, etc. over the wire or plastic grate. Your pump and plumbing will be hidden! No one will no where your water is coming from. You can then connect black PVC piping to the pump (black sprinkler pipe is incredibly inexpensive yet professional looking) and let the water rise up seemingly out of rocks in your yard. You won't have to worry much about pets as the water source is covered with stones. Likewise, you won't have to worry about kids drowning. You can also build a little waterfall over such a pit if you want, just throwing in boulders to hide your electric and tubing, etc. Some people use bamboo for spouts. You can also drill holes through slate (we've found it's really easy if you soak the slate for a day first). Slate is so porous, however, you ought to seal it once you're done drilling. You can also find rocks in nature that already have holes in them.

How Big of a Pump do I need?

Basically, if you buy a fountain at a store you should have instructions on the best size pump for that particular piece of garden art. If you are making your own fountain, here is a rule of thumb: for every inch of width you need to pump 100 gallons per hour. But note that a100 gallon per hour pump is not pumping the same volume at one foot head (elevation above the pump), two feet head, three feet, and so forth. If you are making your own fountain, it is likely you will have to guess which size to buy, and you might be wrong the first time you build one. Most pumps are adjustable but often can be adjusted down only a bit. However, magnetic-driven pumps, the most common kind, are inexpensive and durable. You can find them online at many wholesale pumps outlets.

Wall Mounted Fountains - A Background

!±8± Wall Mounted Fountains - A Background

Just try to imagine the sounds by closing your eyes, picture a woodland location with a bustling river winding its way across the valley and in the distance the water is flowing over the edge of the cliff and down the waterfall. Instantly you can feel calm and relaxed just by thinking of the sounds and the setting, imagine if you could bring the waterfall directly into your living room.

Naturally you would not be able to bring a waterfall into your living room but you could enjoy a wall mounted fountain. Maybe you have never heard of wall mounted fountains, if you haven't then they are superb decorative features that would be suitable for anybodies home. There are many different types and they come in lots of sizes, shapes, colours, styles and designs which gives the buyer the ultimate choice when they are looking to decorate and update their living space.

You may well be asking, what are Wall Mounted Fountains? Many people may not be familiar with them so in very simple terms a wall mounted fountain can be described as an indoor water feature that combines art with the tranquil sound of moving water. The water is distributed over the decorative backdrop providing the sounds of the waterfall and the visuals of a superb piece of modern decor. Using only a very small re-circulating electrical pump this allows the water to be pumped back to the top of the water fountain and redistributed time and time again to provide the effect of the flowing water. The design of the pumps ensures that there is very little noise and will allow the water to be pumped as efficiently as possible throughout the wall mounted fountain feature.

Depending on the size of your room this will have a bearing on the style and type of wall mounted fountain that you would choose. Many rooms such as a living room or dinning room will better suite a wider feature similar to a large picture or painting where as a hall way could most likely suite a longer and thinner feature. When selecting or viewing a wall mounted fountain you need to be careful to visualise the room where you are thinking of locating the feature, think about the dimensions of your room and how it will look in context with your other furniture or wall decorations. Wall mounted fountains provide a brilliant focal point for any room and allow a unique way for you to create a relaxing and welcoming atmosphere for any part of your home.

How to Choose a Pond or Fountain Light

!±8± How to Choose a Pond or Fountain Light

Choosing a Pond or Fountain Light: LED or Halogen?

Basically, there are two kinds of lights available for ponds, halogen lights (which have been around for quite a while), and LED, which are more recent developments. Here are some differences between the two. Note that here we are addressing 12volt systems only.

Some advantages of LED:

Focused light

Solidly built and hard to break, durable

Last twice as long as best fluorescent bulbs and 20 times longer than incandescent bulbs LEDs also are more efficient per watt, produce greater lumens per watt than incandescents or halogen bulbs. LEDs can be built in a number of colors so do not require a filter, which greatly reduces efficiency of light. Finally, LEDs run cooler and are less likely to warm the pond or for their seals to get damaged because of the cooler running temperatures.

Some Disadvantages:

LED lights are still quite expensive and it is taking a while for the price to drop. Also, it is difficult to find an LED system that produces high wattage. Fountain Tech produces the highest pond light wattage we know of at 8 watts per light fixture. And a total of 130 separate LEDs are used in the fixture to do this!

Halogen:

Some Advantages

These are good lights, not as durable as LEDs but pretty durable all in all. The most common sizes are 10 watt, 20 watt, 35 and 50, though you can also find 75 watt lights. You can usually buy lens covers to change the color of the light, though lens filters do reduce the luminosity a great deal. In general, it is more efficient to use colored bulbs. Still, you will find less light from a colored bulb than a clear one. LED is the way to keep luminosity efficient when using colored light. You can find a good selection of both at Cheap Pumps.
Some Disadvantages:

These light bulbs don't last nearly as long as LEDs, though they still last a long time. They burn quite hot and sometimes the high temperatures burn the O-rings and the fixtures leak.

About transformers:

Transformers that will be used outside (as almost all will!) really need a 3-prong plug. Beware of the "for indoor use only" transformer as, in order to find an indoor plug and then run the cable to your fixture outdoors these are often more trouble than the price savings is worth. Find a UL-approved transformer that can be used in or out of doors. That's our recommendation.
