Q: I am building a pond with a waterfall. With so many pump choices, how do I know what to choose?

Linda – Broomall, PA

A: Fun springtime project ahead! As you’re discovering, building a pond with a waterfall involves some planning and careful consideration—which includes selecting a waterfall pump. Your choice is important because it’ll determine how high you can make your waterfall and how much water will flow down it.

You want more than a trickle, right? Before you go pump shopping, crunch these numbers first:

How high will your waterfall be? This measurement is your head pressure, which is the total number of feet from the top of your waterfall to the top of your pond’s surface. If you’re building a 5-foot-high waterfall, for instance, your head pressure is 5 feet.

Pro tip: If the tubing from your pump to the waterfall is longer than 10 feet, add 1 foot of head pressure for every 10 feet. So in the example above, if your tubing is 14 feet, the head pressure would be 6 feet.

2. Flow Rate

How much water do you want pouring over the falls? This number is your flow rate. The average flow rate is 1,500 gallons per hour for every 1 foot of waterfall width. If your 5-foot-high waterfall is 1 foot wide, you should go with a pump that moves around 1,500 GPH; if it’s 3 feet wide, you should go with a pump that moves 4,500 GPH or so.

Pro tip: If you prefer a lighter water flow, calculate 1,000 GPH for every 1 foot of waterfall width. For a heavier flow, use 2,000.

Going Shopping

With those numbers in hand, you should have a pretty good idea what kind of waterfall pump you’ll need to buy. To make the chore easier for you, we recommend:

For lower-flow waterfalls: If you’re designing a smaller waterfall, check out The Pond Guy® MagFlo™ Pump and The Pond Guy® SolidFlo™ Pump. The MagFlo™ line includes 290, 460 and 590 GPH models with maximum head of 6½ to 7½ feet; the low-profile SolidFlo™ line includes 600, 1,200 and 1,600 GPH models with maximum head of 8 to 11½ feet.

For higher-volume waterfalls: If you’ve got a mini-Niagara Falls in the works, you’ll need a beefier pump, like The Pond Guy® RapidFlo™ or the ShinMaywa® Norus® waterfall pumps. The RapidFlo™ comes in 3,000, 4,000 and 5,000 GPH models with 20 to 32 feet of maximum head pressure. The Norus® line includes 3,300 to 11,000 GPH models with maximum head of 19 to 48 feet.

## My stream is already accumulating algae! Is there anything I can use to help clean it up? | Decorative Ponds & Water Gardens Q & A

Q: My stream is already accumulating algae! Is there anything I can use to help clean it up?

Kate – Grove City, OH

A: Yep: It’s algae time! As the spring sunshine melts away ice and snow, the sun’s warmth and light reach underwater to give algae growth a little nudge along. When combined with all the extra leaves (also known as algae food!) that have blown in on windy days and a filtration system that isn’t up to snuff with bacteria, they create a perfect environment for algae accumulation.

So how do you get rid of it when water temps are too cold for bacteria and traditional algaecides?

Step 1: Spring Cleaning

If you haven’t already, consider doing a spring cleanout and starting fresh. Check out this blog post for step-by-step instructions for preparing for and giving your pond a thorough spring cleaning. If you’ve already gotten dirty this season, however, and have found that the algae is unwilling to give up its happy home, move on to step 2.

Step 2: Oxy-Lift™ Defense® to the Rescue

For controlling stubborn algae, pull out your Oxy-Lift™ Defense® pond cleaner. The product’s ingredients have no temperature restrictions, so you don’t have to wait for warmer weather to treat the green nuisance. Simply turn off your stream and, while the algae-covered rocks are still wet, sprinkle on the Oxy-Lift™ powder. Let it sit for 5 to 10 minutes. Before long, you’ll see the algae bubble and break free from the rock. Then turn the stream back on, and use a hand net to scoop out the debris or allow your filter to catch it.

Of course, don’t forget to stick to the basics—particularly as pond season kicks off! Keep your filter running and add the natural bacteria once temperatures are suitable to keep algae growth under control.

## Should I build a pond or a waterfall feature? Which is better? | Decorative Ponds & Water Gardens Q & A

Q: Should I build a pond or a waterfall feature? Which is better?

Bill – Antioch, CA

A: Ahhh… during the heat of the summer, there’s nothing better than sitting nearby the cool, tranquil trickle of running water flowing from your own fountain.

Water features – whether a half-acre pond with a 6-foot waterfall or a small table-top fountain that sits on your deck – create a slice of personal serenity in your yard or garden, as well as drawing birds, dragonflies and other wildlife.

You know you want some of that tranquility for yourself, but before you rent the Caterpillar and start digging, run through these questions, below. They will help you choose the right type of water feature for you.

What kind of budget do you have?

First of all, consider what kind of money you want to spend. In most cases, the larger the water feature, the more expensive it will cost. If you’re unsure, call a pond-building professional in your area to help you assess your needs and determine your budget.

What kind of space do you have?

Next, take a realistic look at your yard. Is it large or small? How can you blend a water garden and fountain into the existing landscape?

If you have a sprawling backyard with room to build, consider The Pond Guy® 11-by-11 or 11-by-16 foot Pond Kit or the smaller The Pond Guy® 6′ x 11′ Pond Kit, all of which include everything needed to build a pond, including fish-friendly rubber liner, underlayment, skimmer, filter, pump, check valve, plumbing fixtures and hardware, and complete instructions. The package even includes some beneficial bacteria to jump-start your feature’s biological filtration.

If you have a postage-size yard or one that’s tightly landscaped, consider a smaller water feature, like one of the Pondbuilder™ Cascading Falls disappearing waterfalls. The kits come in three sizes – 10 inches, 14 inches and 22 inches – and contains a waterfall box, basin, pump vault, pump, liner, underlayment, tubing, waterfall foam, check valve and instructions.

Who will visit your water feature?

Do you have grandchildren or young kids running around the backyard? If so, a waterfall with no open body of water, like the Pondbuilder™ Cascading Falls, would be an ideal choice. You’ll be able to enjoy the sound of running water without the potential danger.

Perhaps, however, you want your pond to be open – thanks to a water-loving dog sharing your house, a blooming love for tropical water lilies or a brand new fish-keeping hobby. If that’s the case, then consider a The Pond Guy® RapidFlo™ Ecosystem Pond Kit or one of The Pond Guy® AllClear™ Ecosystem Pond Kit, both geared toward to do-it-yourselfers.

How much maintenance time do you have?

Finally, think about your schedule and what you enjoy doing. Do you work long hours and simply want a peaceful place for an occasional night on the back porch? Do you like to have the sounds of running water – but without all the maintenance? If so, Pondbuilder Cascading Falls is right for you.

If you’re a gardener, or someone who spends a lot of time outdoors working in the yard, tending your plants and improving the landscape, then one of the pond kits, like a RapidFlo™ Ecosystem Pond or the AllClear™ Ecosystem Pond, should be your pick.
