Water Gardening Information

Ornamental ponds and waterfalls are becoming an everyday part of our landscape. Homes, businesses, parks, zoo's, apartment complexes and office buildings. Everywhere we look people are wanting to add water to their landscape.  And for good reason since few other things are as relaxing as the sound of splashing water. For centuries other parts of the world, such as Europe, have used water as the focal point of their landscaping. This trend is now catching on in the U.S. as well.

EasyPro is one of the countries largest suppliers of pond and waterfall products to the landscape contractor/garden center market. We have seen an explosion of interest and demand for pond products over the last few years. Because this industry is young there is still a lot of confusion and misinformation about the proper way to construct a pond. Your pond is an investment that, if properly done, will provide years of enjoyment, or if improperly done will provide years of headache.  EasyPro has been in the fish and pond business for over four decades.  Combined, our staff has nearly 150 years of experience that you are welcome to draw from when designing your "dream pond". Whether building a new pond of maintaining an existing one, you can rely on us for all your aquatic needs.

Pond Location

Meijer Garden

Your pond should be located in a spot where it can be enjoyed the most. Locating the pond near a window or along side a deck will allow you to enjoy the pond more than if the pond was located out in the middle of the yard.

Ponds should not be located in the low spots in your yard. These low spots gather rainwater runoff, something you do not want in your pond.

Most books will tell you ponds need at least four to six hours of sunlight per day for proper plant growth. While aquatic plants (lilies, cattails, etc.) prefer sunlight they will do just fine in shady areas as long as slow release aquatic fertilizer tablets are added a couple of times per year. Shady ponds tent to have less algae problems.

Do not build a pond too close to a tree. Building a pond inside a tree's "drip zone" can damage tree roots. Tree roots will not grow through or puncture a pond liner.

A pond is not complete without landscaping. Locate your pond so there is ample room to landscape around it. It will take some time after your pond is installed for the plants to fill in and complete the setting.

A waterfall and/or stream should be located at the back of the pond. This will allow you to see the water feature as you approach the pond as well as increase the sound of the splashing water.

Large Pond

Waterfalls are a beautiful addition to any pond. The sound of splashing water is amazingly relaxing. Waterfalls add oxygen to the water and provide a large area for beneficial bacteria to grow on.

Simply don't over do it, often people try to create too large a waterfall. If your ground is flat, your waterfall should only be two to three feet tall. If your ground has a natural slope to it, you can build a much larger waterfall and still have it look good.

Ponds and waterfalls need to be as natural as possible. A six foot high waterfall located in a flat yard will look out of place. Try to blend your pond into the surrounding landscape.

Don't build your waterfall and/or stream too narrow or straight. Again, make your stream look natural by creating twists and turns and by using different sizes of rocks. Often people stack flat stones on top of each other and in a straight row. This creates a "chimney" look and very seldom looks natural.

A separate piece of liner is typically used for the waterfall/stream. This liner does not need to be glued to the pond liner as long as the joint overlap is running downhill. Be sure the stream liner is over the pond liner.

Expanding foam is a must. Traditionally people use mortar to secure their rocks. Instead, we have found that expanding foam works better and lasts longer.

Ornamental ponds often need supplemental filtration to maintain proper water quality. Filtration involves two parts: the first step is mechanical. This step removes particles from the water like leaves, grass clippings, dead plant foliage, etc. The pond skimmers are by far the best mechanical pond filter we have seen yet. Biological filtration is the second stage and is especially important for ponds with fish. Biological filtration keeps the water healthy and clear. The filter media inside a bio-filter collects beneficial bacteria which cleans the water as it passes through the filter.

Sizing Your Filter
All pond filters are rated for maximum pond size or maximum GPM flow. To properly filter the pond your filter needs to be able to filter half the pond volume per hour.

Example: A 1,000 gal. pond would need a 500 gal. per hour filter.)

Filter Location
We recommend using an external biological filter. This filter can be located directly next to the pond or concealed by plants, rocks or bushes away from the pond. Water is pumped from the pond through piping to the filter and then back to the pond. Our aquafalls filters are ideal since they bury in the ground for easy concealment, require minimal cleaning, and provide an ideal base for your waterfall/stream.

Aquatic plants are an important part of the filter system. Plants absorb nutrients from the water thereby reducing the nutrient load in the pond which helps your filters. Oxygenating plants are especially beneficial because they not only filter, they also add oxygen to the water.

UV Sterilizers
Ultraviolet clarifiers (UVC) are a popular way to control pea soup colored water. Pea soup green water is caused by an excess of free floating algae cells. UVC's destroy all living cells in the water as it passes through the UVC. If you are adding bacteria to your pond, you will want to shut off the UVC before adding the bacteria, then restart after 24 hours.

Pond Liners

Pond Liner

Flexible pond liners are by far the material of choice for the do it yourselfer. Using a flexible liner does not limit you to a specific size and shape as the preformed ponds do. EPDM Pond Liner is the #1 choice for water gardening because it is very flexible, very puncture resistant and is long lasting. For lining large ponds we recommend the polyethylene material because it is light weight, easier to handle and costs less than rubber. Also, polyethylene liners can be made up to 60,000 sq. ft. in one piece.

Measuring For Your Liner:
For a water garden, add the depth twice to both the length and width, then add at least 1' to both numbers for liner overhang. For a large pond, add the depth at the deepest point to the length plus the width. Then add 5' to each figure to allow for burying around the edges.

Example: Pond size 30'W x 50' L x 10' deep
Width = 30' plus 10' (depth) plus 5' (burying) = 45 '
Length = 50' plus 10' (depth) plus 5' (burying) = 65'

Devos Large Pond

Always try to line your pond with a one-piece liner. There are special tapes available for seaming liners together but do this as a last resort.

Choose a Quality Liner. Our EPDM liner has a 20 year warranty. Think about it — trying to save a few dollars on a cheap quality liner may well cost you a lot of time and aggravation in the end. If your liner cracks of punctures easily, you will have to drain the pond, remove all stones and the old liner and start all over. Save yourself the time and money, use quality materials the first time. Our 45 mil rubber liner, when installed with the protective underlayment beneath it, will provide years of enjoyment for you.

We have found that covering the liner in a water garden with natural fieldstone will help protect the liner from sunlight, animals, etc. Ponds also look better with a natural stone bottom and if your water level drops a few inches you won't see a strip of liner exposed around the top of the pond. The stones also provide a large surface area where beneficial bacteria will grow and help clean the pond's water. We recommend covering the liner in water gardens with 3" - 6" fieldstone then sprinkle 1" stone over the pond to fill in the cracks between the larger stones. Feel free to mix in some larger stones here for a natural looking water garden.

Building "Smaller" Reservoirs...


It's common knowledge that a reservoir has to be built large enough to hold adequate water for the size feature you are building. On large projects like the one to the left the reservoir can get pretty big. Making a natural looking stone bottom can be a challenge.

Throughout 2009 EasyPro designers often have oversized the liner on the reservoir which allows you to wrap liner over the top of the cubes and greatly reduce the size of visible stone area.

This 50' long stream has a reservoir that is much larger than the small visible rock area at the bottom suggest. Extra liner was wrapped over top of the res-cubes shrinking the size in half.
