What is waterfall foam? | Decorative Ponds & Water Gardens Q&A

What is waterfall foam?

What is waterfall foam?
Krystal – Howell, MI

When you build a backyard waterfall, it’s important to remember that, unlike a natural waterfall, every drop of water that cascades down the face of your mini-Niagara is delivered by a pump. In order to make that limited supply of pumped water – and your waterfall – look as dramatic and beautiful as possible, it helps to seal up the nooks and crannies behind and between rocks. And that’s just one of the places where Waterfall Foam comes in handy.

When applied carefully, Waterfall Foam seals the areas beneath and around rocks where water naturally flows. When those areas are sealed, water is diverted over the tops of the rocks, making the waterfall look fuller and more beautiful. In addition to its aesthetic benefits, Waterfall Foam also helps to secure and stabilize larger rocks, which in turn reduces maintenance.

But why use Waterfall Foam instead of hardware store spray-foam insulation? First and foremost, hardware store foams are formulated as insulation – and their chemical ingredients can be harmful or fatal to fish and plant life. Waterfall Foam is carefully formulated to be fish and plant safe. Second, hardware store foam simply isn’t designed to blend in – where Waterfall Foam looks natural, and works wonders to enhance the look and longevity of your waterfall.

Water Features That Fit

Creating a water feature is a fun and exciting process consisting of endless designs and limited only by your imagination. Many people think they are have to have a large amount of land to create a great water feature. In reality, a beautiful water feature can be constructed in even the smallest yards or even indoors. Before you start purchasing materials for your pond project, sit down with a pen and paper and take some time to research and design the perfect water feature that fits your situation.

One of the more common ways people ease their way into pond building is by using a preformed pond basin. I am sure most of you have seen them when walking through your local home & garden stores. These plastic liners are available in a wide array of shapes, sizes and depths which appeals to customers looking to install a pond in a limited amount of space. These liners are great for people new to ponds as the shape and dimensions are already figured out for you. This does however limit your creative influence on your soon to be pond. It is for this reason that more and more brave newcomers opt to install Rubber EPDM liner instead. Using rubber liner allows you the freedom to create whatever size pond you desire, filled with curves, plant shelves and waterfall streams. The rubber liner is flexible and therefore is not prone to cracking like the harder plastic performed liners. Rubber EPDM liner can also be pieced together using a Seam Kit to accommodate a large array of designs. Pond Kits are packaged with 45Mil EPDM Rubber Liner to create ponds as small as 8’ x 11’ or as large as 21’ x 26’. You can also purchase rubber liner in 5’ increments for smaller or larger applications.

Those of us who enjoy the sounds and sights of flowing water but are not thrilled by the prospects of managing an entire pond, have other means of entertainment. Using a small basin and a pump, you can create a beautiful, streaming waterfall that disappears into a hidden reservoir underground. We call this a pondless waterfall. The great thing about pondless waterfalls is that they can adapt to smaller areas very easily because there is no standing water. For instance, if you don’t have much of a yard and would like to hear the sound of water, a pondless waterfall is for you. There are Pondless Waterfall Kits available that contain all of the parts you need to get started and are available in different sizes.

When planning to build your water feature, plan for a weekend, one preferably without rain of course. Most smaller Pond Kits and Pondless Kit usually need only a weekend to complete and right now is usually the most popular time to build. Just remember it is far easier (and cheaper) to work with your pen and paper in the planning stages than it is once you start building your water feature. Planning ahead helps prevent any unwanted surprises.

Waterfall Foam – Decorative Ponds & Water Gardens Q & A

Waterfall Foam

Foam Sweet Foam

The key to constructing a quality water garden, or anything for that matter, is to use the proper tools. While you may be able to fashion a lot of your own components or incorporate random on hand materials into your pond build you can miss out on potential benefits that result from years of product testing and development as well as functional design. While this holds true for anything from skimmers, filter media, and waterfall boxes, it is also true of small scale materials like waterfall foam.

Waterfall foam is primarily used to aid in the placement and retention of stone in your water garden and to seal gaps between these stones to manipulate the flow of water down the waterfall and along the streambed. Simply put, the foam expands between your rocks keeping the water from flowing behind them. As the foam dries it also holds the rocks firmly into place so you don’t have to worry about stones washing downstream with the flow of water, rock collapse from seasonal shifting or the displacement of loose perimeter rocks.

12oz cans are available for one time use and include an application tip. You simply place the tip between gaps and crevices and pull the trigger to release product to the desired area. You can also use it as an adhesive to hold stones in place. Any excess foam that protrudes from between the rocks can easily be trimmed away. Another great aspect of using waterfall foam is that if you mess up, or decide to change the location of some of your rocks, you can still cut away the foam and re-arrange them. The foam is black in color to blend in with the surroundings and is plant and fish safe. For contractors, or those of you who change your minds a lot, you can purchase a Foam Gun and use 24oz cans which can be used in more than one application. If you decide to use a foam gun you will want to maintain it by cleaning it with Foam Gun Cleaner between uses.

How can I keep my waterfall free of algae and buildup? – Decorative Ponds & Water Gardens Q & A

How can I keep my waterfall free of algae and buildup?

How can I keep my waterfall free of algae and buildup? Renee – Heber Springs, AR

While the warm sunny weather is great for enjoying the outdoors this summer, it can also create some headaches in your water garden. A lot of you may notice that your stream and waterfalls are growing a nice coat of green algae as we continue through the warmer summer months. In a lot of cases, especially if you are using beneficial bacteria such as Nature’s Defense your water is clear but algae and debris is attaching itself to your stream, waterfall and rocks. There is really simple fix to this green monster, in less then 15 minutes you can have amazing results.

It’s simple, use Pond Logic Oxy-Lift Defense direct to your waterfall, stream, or anywhere you have debris or algae accumulating. When used on damp areas, the Oxy-Lift Defense will lift stuck on debris and algae off their attached surface so they can be easily rinsed away avoiding the need for a pressure wash or tough manual labor. Simply shut down your waterfall and quickly remove any debris or algae with your hand, then sprinkle on the Oxy-Lift, you’ll be able to hear the Oxy-Lift working to break the debris off the rocks. After 10-15 min restart your waterfall. You can scoop the loose algae out of the pond or let your skimmer do the work. We recommend applying Oxy-Lift later in the day when you will not be viewing the pond as the pond may become a little cloudy or foamy for a short period of time. Regularly cleaning your waterfall will ensure that maintenance is short and sweet keeping you from having to spend hours trying to wrestle your stream and waterfalls into submission.

If you are having issues with algae not only on the stream but also in the pond itself you can also apply a dose of Tetra Pond Algae Control to quickly kill undesirable growth in the pond even if it contains fish and plants! Using the proper products to maintain your pond will save you time and money in the long run and ensure a faster turn around process should your pond find itself in an algae attack? While algae blooms can not always be prevented the duration and intensity of their visit can drastically be reduced when your pond is properly kept. For best results consider the DefensePAC it includes everything you need in one simple package such as Nature’s Defense, Oxy-Lift, Clarity Defense, Muck Defense, and Seasonal Defense.

More Than Just A Pretty Face

Maybe you’ve entertained the idea of constructing a water garden in your yard, but feel you are not quite up to the task. Perhaps you are one of those people who don’t understand what all of the “hype” is about when it comes to back yard waterfalls and pricey Koi. To those of you who have yet to experience the triumphs and challenges of owning your very own water garden, there really is more to pond ownership than fish, water, and rocks.

Thanks to the progression of the pond industry, both the process of selecting an appropriate type of water feature and the installation procedures associated with each style have been dramatically simplified. This broadens your selection to a wide range of water features from small pre-formed ponds for beginners, low maintenance and space saving Pondless Waterfalls, or large water gardens equipped with intricate streams and waterfalls for those of you with more experience or are daring. You can also take advantage of the cost savings of purchasing a complete Pond Kit which can save you the time and trouble of trying to purchase each component independently. Regardless of which type of pond you decide is best for you, remember to take your time and do your Homework. Being prepared will ensure that the entire pond process from design to finished product is an enjoyable experience.

When done properly, a water feature can become an outdoor retreat, providing soothing sounds and sights to create a calm and relaxed atmosphere. Your water feature will accent your home and the surrounding landscape creating an inviting appearance and an increased curb appeal. Implementing Aquatic Plants and Koi into your water feature is a great way to further increase its value. Having fish present in your water feature creates fun activities that you can do with friends and family. Witnessing a few fish antics alone provides a great source of entertainment, while feeding your fish is an excellent group activity that can create a little extra “together” time with friends and family. If you have children it is also a great way to teach them about the responsibilities of pet ownership.

Every person has their own unique story about how their water feature came to exist. For some it may just seem like a logical step and for others it starts with the gift of one small goldfish. Intentional or not, it is easy to fall in love with your water feature. While there is some time and expense associated with any water feature, it all seems trivial once you see the results of such a rewarding investment.

What does filter media do for my water garden? – Decorative Ponds & Water Gardens Q & A

Q. What does filter media do for my water garden? – Debbie in Illinois

Keep It Clean
With all of the pads, balls and nets in this blog you might think The Pond Guy has hung up his waders and opened a sporting goods store. Not to worry pond guys and gals, we are of course talking about filter media in your water garden.

Hey! Nice Pad!
When you look inside your filter, whether it’s a waterfall filter or pressurized filter, you may notice there are assortments of pads, balls, etc. These are called filter media. This filter media serves a vital purpose in any water garden.

Bio Blox Filter MediaFilter media are specifically designed to help colonize a ton of natural bacteria in a small area. As fish excrete waste, ammonia levels began to rise. Without enough natural bacteria, ammonia levels can become so high your fish will become stressed which can eventually to death. Natural bacteria will grow in a water garden without filter media, but unfortunately it is very minimal and never enough to keep up with high ammonia levels.

Less IS More
Many pond owners often think that a clean filter pad will lead to a cleaner pond. This is not the case. As it takes several weeks for nitrifying bacteria to colonize, many pond owners often clean their filter media as soon as it gets dirty. This unfortunately defeats the purpose of the biological functions of the filter media. Some of our readers have written in telling us that this buildup is even blocking or restricting water flow. It is most likely debris or algae being picked up from the water, not the bacteria causing this issue. If necessary, to clean filter media we highly suggest removing the filter media from the filter and placing into a bucket of “pond water” and gently swish the media back and forth. Do not scrub, or use tap water to clean the filter pads. Again, this will cause a loss in natural bacteria. If you accidentally do clean your filter pads, you can use PL Gel on your filter pads to colonize the bacteria faster. It is known throughout the pond industry to reduce colonization by up to 80%!

To prevent blockages to your biological filters use a pump pre filter or a skimmer which includes a net or debris basket along with its own filter pad. This will prevent large debris from getting to your filter. Vacuuming will pick up debris and muck from the pond floor also preventing clogs. Placing these “pre-filters” as buffers will ensure a shorter, easier cleaning time as well as make certain that your beneficial bacteria are left alone to flourish and protect your water garden.

Spring Accessories – Decorative Ponds & Water Gardens

Dyed Pond


Behind The Springs
It is truly an enjoyable experience taking in the sights and sounds of a water garden. Crystal clear water, brilliantly colored fish and lush green plants all meld together to create a picture perfect landscape. While water gardens are a wonder to behold, pond guys and gals everywhere are working hard to keep them looking their best all season long. Let’s take a behind-the-scenes look at some of the accessories that make that work a little less… well… hard!

What’s Your Net Worth?
Having a pond net handy for regular maintenance is a surefire way to add some ease into your cleaning regimens. Purchasing a tool like our 4-in-1 Interchangeable Pond Net not only allows you the ability to skim floating debris from your water gardens surface, but also gives you accessories you can use to round up and relocate your fish for large scale clean ups and to clean seasonal build up from hard to reach surfaces. The added benefit of a telescoping handle ensures that the areas you need to clean are within reach. Remember, the objective of using tools is to make work easier on you. Purchase items that perform for you and work best for your specific situations.

Sayonara Sludge!
Giving your water garden a thorough cleaning in the Spring will help reduce the chances of dealing with excess algae growth and overall improving the quality of the water in your pond. Simplifying the cleaning process using the correct tools encourages us to perform our cleanings a bit more enthusiastically. While Spring cleaning is not the most enjoyable pastime for water gardeners, it can be way more convenient (and way less painful) with a pond vacuum. Vacuums like the Pond-O-Vac IV clean the built up muck from your ponds bottom while eliminating time spent bent over scooping and scrubbing. Adding beneficial bacteria like Pond Logic® Nature’s Defense® & Muck Defense® when your water temperatures reach 50 degrees or higher will naturally break down organic debris that eventually turn into muck at your ponds bottom. Preventing sludge build up will result in easier and less frequent cleanouts throughout the season.

Using Some Colorful Expressions
So maybe this is your first season, or you are looking to add a special touch to your water garden. Implementing a variety of aquatic plants and shoreline grasses will add some color to the landscape and will have a positive impact on the water quality in your pond. Floating plants like Water Hyacinths or Water Lettuce will consume the same nutrients as algae that are present in the water column, reducing the amount of food available for potential algae blooms. Submerged plants like Hornwort give your fish an excellent place to hide. Try to include a diverse selection of plants to boost your water garden’s visual appeal and promote a balanced ecosystem.

Another great way to accent your water feature is to install pond lighting. When it comes to shedding some light on your project, it can be as simple as adding a couple Solar Floating Lights to set the tone, or installing a series of Waterfall Lights and some 50-Watt Pro Lights to highlight the surrounding landscape. With a wide assortment of lighting styles to choose from including Halogen, LED, and colored bulbs, you can achieve a unique look that fits exclusively to your pond!

How Do I Get Debris or Algae Off of My Water Garden’s Rocks, Streams & Waterfalls? – Water Garden Q & A

Q: How do I get debris or algae off of my water garden’s rocks, streams and waterfalls? – Several Customers

A: As the Summer progresses, the weather gets hotter and algae begins to grow on your streams, waterfalls and rocks. Sometimes using AlgaeFix just isn’t enough to remove the algae from the rocks. It will kill the algae, but the algae stays stuck to the rocks. It seems sometimes you need a steel wool brush to scrub the algae off.

My suggestion, when you have debris of algae on rocks, is to use a product called Oxy-Lift. Oxy-Lift is designed to lift these debris off of rocks for easy removal.

Simply turn your pump off and sprinkle the affected areas with Oxy-Lift. Wait 10 minutes and turn your pump back on. You may need a hose to spray away the additional debris, but no more scrubbing! If you have a skimmer installed in your pond, it will catch the debris as they are washed in by the waterfall. Or you can skim it yourself with a skimmer net.

How Do I Properly Size a Pump to Create the Waterfall I’m Looking For? – Water Garden Q & A

Picture of a Waterfall

Q: How do I properly size a pump to create the waterfall I’m looking for? – Several Customers

A: We get this question asked to us quite a bit. The following process will help you in determing the correct pump size for a waterfall:

Step 1: Determine the Head Pressure (Head)

Head equals the total number of feet from theCalculating Pump Size Chart top of the waterfall to the water’s surface. For example: Let’s say that height is equal to 5′.

Step 2: Determining Desired Water Flow
In general, you will need 1,500 gallons per hour (gph) for every 1-foot of waterfall discharge for an average flow. The discharge is considered where the water enters back into the pond. For example: Let’s say the width of our waterfall is 2′. This would mean we need a pump of approximately 3,000 gph.

Step 3: Putting It All Together
In our example, our head pressure is 5′ and the approximate gph of our desired pump is 3,000 gph. This means would need a pump that would pump 3,000 gph at 5′ of head.

Other Notes:

  • For a heavy waterfall flow, use 2,000 gph per foot of waterfall discharge.
  • For a lighter waterfall flow, use 1,000 gph per foot of waterfall discharge.
  • If the tubing from the pump to the waterfall is greater than 10′ then it is recommended to add 1 foot of head for every 10′ of tubing.
