Q: How do I calculate what size basin I need for a pondless waterfall?

Robert – Waverly, TN

A:  With the help of a few friends, installing a pondless waterfall is an easy way to upgrade your land- or waterscape. If you are planning to design and build your own feature, here’s how to do the math to determine your basin size.

 

Step 1: Calculate total amount of water in your stream

Sound tricky? It’s not. To calculate the water that’s in motion in your stream, first measure your stream’s length, width and depth. Then plug those numbers into this equation: L x W x (0.25 x D of stream, generally 1 to 2 inches) x 7.48.

Here’s an example. If your stream is 25 feet long, 2 feet wide and 1 inch deep, the equation would look like this: 25 x 2 x (0.25 x 1) x 7.48 = 93.5 gallons.

Step 2: Calculate amount of water your basin needs to hold

As a general rule, you will need your basin to hold 2½ times the amount of water in your stream. To find out how much water your basin will need to hold, multiply the gallons of water in your stream by 2.5. In the above example, it would be 93.5 x 2.5 = 233.75 – so your basin would need to hold 233.75 gallons of water.

Step 3: Determine the size basin needed to hold the water

Here’s where things get a little tricky. You’ll likely use boulders, stones and other décor in your design. Well all that rockwork will take up space for water, and so you’ll need to go with a larger vessel.

Try this quick equation that will help you determine what size basin you’ll need with boulders: L x W x D x 2.2 = gallons of water the basin will need to hold. To give you an idea, a 5 foot by 10 foot basin that’s 3 feet deep and contains stone will hold 330 gallons of water.

A space- and cost-saving option is to use a basin matrix in place of some of the boulders. A basin matrix is a strong, 27-by-16-by-17½-inch hollow box that’s perforated with half-inch holes to allow water to collect and pass through. You can stack them together and landscape right over them. Each basin matrix holds 31.5 gallons, adding valuable water volume without increasing the size of the basin. Don’t forget to add a pump vault for easy access to your pump.

Go with a Kit

If you aren’t trying to customize a large waterfall, consider investing in a pond free waterfall kit, like PondBuilder™ Cascading Falls Pondless Kits. They contain all components you’ll need – from underlayment and liner to a waterfall box, pump, basin matrix and plumbing – with predetermined dimensions to help you create your water feature.

What can I do to help out a fish that was attacked by a heron? | Decorative Ponds & Water Gardens Q & A

Q: What can I do to help out a fish that was attacked by a heron?

Q: What can I do to help out a fish that was attacked by a heron?

Lori – Glen Forney, PA

A:  Ouch. A heron attack isn’t pretty – and it’s potentially deadly to your fish. Unfortunately, you can’t call 9-1-1 or an emergency fish veterinarian for a pond call, but you can try some things that could save your pet’s life.

 

  1. Examine, Triage: The first thing to do is examine the victim and do some triage. Capture the injured fish in a pond net and take a closer look at its wounds without removing it from the water. How severe is the injury? Are there just a few scrapes, or does the fish have an open wound?
  2. Minimal Injuries: If your fish’s injuries aren’t too severe and it appears to be normal except for a few scrapes, leave it in the pond and add some Stress Reducer PLUS to the water. The liquid formula will help to calm the fish and rebuild its slime coat, which defends it against infection. You might also want to add some soothing salt to the water (read about it here).
  3. Remove and Isolate: If your fish is severely injured, set up a quarantine tank with pond water and an aerator, add some Stress Reducer PLUS, put it in a shaded and protected area, and gently move the fish from the pond to the tank.
  4. Watch for Infection: Keep an eye on your fish while it’s in the quarantine tank. Because damaged tissue becomes a breeding ground for bacterial and fungal pathogens, watch for signs of infection. If you see split or ragged fins, slimy patches or red ulcers on its body, or any other unusual symptoms, use CrystalClear® Wipeout™ or PondCare® MelaFix to heal the wounds and restore damaged tissue.

While your finned friend is recovering, makes some plans for how you’ll guard your pond against future attacks. A Blue Heron Decoy will dissuade the real things from stopping by for a snack. Pond netting will prevent birds from reaching the water. Floating, submerged and marginal aquatic plants give your fish somewhere to hide, as do fish shelters, like the Koi Kastle. Set your fish up for safety – especially since that heron will be back for seconds!

I would love to have ducks at my pond. Is there any harm, and how do I attract them? | Ponds & Lakes Q&A

Q: I would love to have ducks at my pond. Is there any harm, and how do I attract them?

Q: I would love to have ducks at my pond. Is there any harm, and how do I attract them?

Jerry – Cass City, MI

A: Ducks certainly make an entertaining and colorful addition to a pond or lake. Various species of these plumed wetland visitors grace just about every continent and climate on planet earth – including sub-Antarctic islands like South Georgia and the Aucklands to oceanic locales like Hawaii and New Zealand.

Despite their worldwide distribution, getting ducks to call your pond home can be a challenge. But you can attract them if you understand their specific needs.

Pondside Open House

The duck types that frequent ponds include mallards and wood ducks, along with Muscovy ducks, black-bellied and whistling ducks. Ducks are omnivores and like to eat a wide range of foods, from small fish, eggs, snails, worms and bugs to grass, weeds, seeds and berries. In general, they require a lot of space and copious amounts of water in the form of marshes, lakes or large ponds. Aquatic plants, like reeds and water lilies, make them feel at home, as does concealed areas with tall marsh grass and shrubby cover for nesting and hiding.

Attracting the Flock

Providing a duck friendly habit is the best way to convince the feathered visitors to stop by, but here are some expert tricks to make your pond more appealing:

  • Create a Mess Hall: Set up feeding areas by clearing out an area or providing large, low platforms, and toss out some cracked corn, spilled birdseed and kitchen scraps. Don’t feed them by hand, but use goodies to pique their interest.
  • Plant a Duck Garden: Berry bushes can help draw ducks. And if you have a garden area near your pond, use mulch to attract tasty insects and earthworms.
  • Offer a Nest Box: Though ducks will nest in a variety of places, from ground nests in grassy areas near the pond to brush piles and hollow logs, provide them with nest boxes to help attract nesting ducks.
  • Install a Fountain: Ducks flock to the sound of splashing, so consider installing a fountain or waterfall in your pond.
  • Use Natural Décor: Add some half-submerged logs, overhanging shelves, marsh grasses and marginals, aquatic plants and brush piles to your landscape.
  • Add Some Decoys: A duck decoy pair floating quietly on your pond will attract the attention of the real-life things. They’ll swoop down to investigate and (hopefully!) decide to stay for a while.

Duck Dangers

Unlike a Great Blue Heron, ducks will leave your fish alone – but they can trigger other problems. If a lot of them are visiting, they can cause water quality issues (which can be remedied with the beneficial bacteria in Pond Logic® PondClear™). They could bring in unwanted weeds, like duckweed and water milfoil, that weren’t present before. The ducks, ducklings and eggs could also attract feral cats, raccoon, skunks and other predators.

Having these colorful beauties visit your pond, however, is worth the hassle. When they do stop by, observe them from a distance – and enjoy bird watching!

I have an old sump pump. Can I use it to create a fountain for my pond? | Ponds & Lakes Q&A

Q: I have an old sump pump. Can I use it to create a fountain for my pond?

Q: I have an old sump pump. Can I use it to create a fountain for my pond?

Nick – Linwood, KS

A: Sounds like you want to do some “upcycling” and save a little money while making use of old equipment that’s sitting around. What a fun project, and something you can show off to your friends!

Yes, you can certainly transform that old sump pump into a fountain for your pond – but whether it works will depend on what you want to do with that fountain.

Sump Pump Fountain?

A sump pump is traditionally used to remove water that’s collected in a basement. It pumps the water away from the house to a place where it’s no longer problematic. It’s not really designed for long-term continuous use, and so using a sump pump to create a spraying fountain might decrease its life expectancy. Replacing it could be costly.

There are other factors to consider, too. A sump pump might cost more to operate. You’ll still need to create a way to anchor or suspend the motor and create a spray. And you’ll need to extend the power cord long enough to reach a power source safely – which will require trial and error or fancy engineering.

If you’re a build-it-yourselfer in search of a challenge and plan to not use it for long-term continuous use, go for it! If not, consider purchasing an actual fountain.

Out-of-the-Box Easy

For those who are looking for an easy, cost-effective and trouble-free way to add some splash to a pond, buying a pre-manufactured decorative fountain has its benefits, including:

  • They come with pumps that are designed to be used as a fountain, so they create much more water movement and a heavier spray that’s less affected by wind and pump-clogging floating debris.
  • They can be used as an aeration system in ponds less than 6 feet deep.
  • All the engineering work is done for you! After a quick installation, you’ll have a decorative spray and a power cord that’s long enough to reach the shore.
  • Some, like the AquaStream™ Fountain and Light Combo Kits, come with decorative options, like lights and different spray patterns.

Whichever you choose, it’s always a great idea to create movement and aerate the water. Your fish and plants will appreciate it, and you – and your guests – will, too!

What is the difference between a waterfall filter and a waterfall spillway? | Decorative Ponds & Water Gardens Q & A

Q: What is the difference between a waterfall filter and a waterfall spillway?

Q: What is the difference between a waterfall filter and a waterfall spillway?

Ashley – Forest Grove, OR

A:  Waterfall filters and waterfall spillways both generate a flowing waterfall in your pond or water feature – but they have different designs and purposes. Here’s what you need to know about including them in your waterscape.

 

A Waterfall Filter

A waterfall filter, like The Pond Guy® ClearSpring™ Pro Waterfall Filters, serves two purposes: it generates a waterfall, and it houses your biological filtration system. The waterfall filter provides a starting point for the waterfall itself as the water fills its deep basin and pours evenly over the spillway. That basin is also spacious enough to hold filter media, which houses countless beneficial bacteria – a.k.a. your biological filtration system.

These two-in-one units work well for hobbyists who are building a new pond or are in need of additional filtration. Once you install one, be sure to seed the filter media with PL Gel, a bacterial inoculant that contains beneficial microorganisms and naturally occurring biopolymers that reduce filter startup time.

A Waterfall Spillway

A waterfall spillway, like the PondBuilder™ Elite Cascade Spillways, also provides a starting point for an evenly pouring waterfall, but the basin itself is smaller and provides no room for filter media.

But because it creates the environment-enhancing movement and sound of flowing water, a waterfall spillway makes an excellent addition to a pond that’s already filtered. It also works well for pondless waterfalls and in ponds in areas with little room to work.

Customizing Your Flow

Whether you install a waterfall filter or waterfall spillway, they can both be used in conjunction with a skimmer. You can also easily blend them into your landscape with rock covers or aquatic plants while still allowing you to access the unit. Some models even offer a planting shelf or basket to house additional aquatic plants. Check out our entire selection of Waterfall Filters & Waterfall Spillways.

What are some common types of baitfish used in ponds? | Ponds & Lakes Q&A

Q: What are some common types of baitfish used in ponds?

Q: What are some common types of baitfish used in ponds?

Steven – Johnstown, OH

A: If you stock game fish in your pond or lake, you better know your baitfish. Used as food for larger predatory game fish, these small swimmers are typically common species that breed rapidly. They’re easy to catch, easy to supply and easy to stock.

Freshwater baitfish include any fish of the minnow or carp family, sucker family, top minnow or killifish family, shad family, and some fish from the sculpin or sunfish family. Some common types that you’ll see in a recreational lake include fathead minnows, golden shiners, creek chub and white suckers. Let’s learn more about these specific types of fish and how to fatten them up for your bass and trout.

Fathead Minnow

The fathead minnow (Pimephales promelas) is a species of temperate freshwater fish whose natural geographic range extends throughout North America. The golden, or xanthic strain known as the rosy-red minnow, is a very common feeder fish sold in the United States. In the wild, the fathead appears dull olive-gray with a dusky stripe extending down its back and side. These guys will eat just about anything, and they prefer a water temperature of 50 to 70 degrees Fahrenheit and a pH range of 7.0 to 7.5. Its main predator is the northern pike.

Golden Shiner

The golden shiner (Notemigonus crysoleucas) is a cyprinid native to eastern North America. In the wild, these bait fish grow to 3 to 5 inches long and have dark green to olive body with a silvery white belly. They prefer quiet, weedy waters and are fairly tolerant of pollution, turbidity and low oxygen levels. They can tolerate temperatures as high as 104 degrees F – which is unusually high for a North American minnow – and they nosh on zooplankton, insects, plants and algae. Predators include trout and bass.

Creek Chub

The creek chub (Semotilus atromaculatus) is another type of minnow that’s found in the eastern United States and Canada. Growing up to 6 inches, they typically have a dark brown body, sometimes with brown spots, with a white lateral line. These hardy bait fish, which prefer water temperatures between 35 and 90 degrees F, gravitate toward weedy areas and prefer stream or river environments rather than lakes. They’ll gobble just about anything – including fish, insects, larvae and vegetation. Predators include trout and northern pike.

White Suckerfish

White suckerfish (Catostomus commersonii) are found in small streams, rivers and lakes in the Midwest and east coast of the United States. Reaching lengths between 12 and 20 inches, the white sucker has a dark green, gray, copper, brown or black-brown body with a light underbelly. They’re bottom feeders, and they’ll use their fleshy lips to suck up bottom sediment and other organisms that live there, including small invertebrates, algae and plant matter. Predators include walleye, trout, bass, northern pike and catfish.

Using Baitfish

When it comes to using bait fish, you have two options: stock your pond with them and keep a separate supply on hand to use when you do some fishing.

To stock your pond with bait fish, purchase a supply from your local sports shop or pet store and introduce them to your pond or lake after acclimating them. Be sure to provide a fish habitat for them, like one of the Honey Hole Attractor Logs, Shrubs or Trees, so they can safely reproduce (and fatten up!) and keep the population thriving.

In addition, grow bait fish in a separate tub or tank for use when you’re fishing. Be sure to keep the water cool and fresh to reduce stress, and keep the oxygen levels high with a bubbler. They might be able to tolerate less-than-ideal conditions, but that doesn’t mean they shouldn’t be without their O2!
