How often are you really supposed to wash out your filter? | Decorative Ponds & Water Gardens Q & A

Q: How often are you really supposed to wash out your filter?

Q: How often are you really supposed to wash out your filter?

Al – Greenville, RI

A: The filtration system in your pond is made up of two parts: the mechanical filter and the biological filter. They both clean and clarify the water, but they do so in very different ways and require very different cleaning regimens to keep them optimally operating.

The Mechanical Filter

The skimmer or pump sock make up your mechanical filter. Able to function at all temperatures (as long as the water is liquid), their main purpose is to catch larger debris, like chunks of algae, leaves, foliage and other things that blow into your pond and settle on the water surface. These items are collected in a mat or debris net/basket as the water passes through the mechanical filter, which then protects the pump from clogging.

Cleaning the mechanical filter is easy. You simply remove the mat or debris net/basket, dump out the debris and rinse it with a garden hose. This can be done as often as you like or as needed when you see the water flow slow down. In fact, checking it often is a good idea, particularly in spring and fall when debris tends to collect in a pond.

The Biological Filter

Your waterfall box, pressurized filter and in-pond filter filled with beneficial bacteria-covered filter media make up your biological filter. Their main purpose is to break down tiny, suspended debris, resulting in crystal clear water.

Here’s how it works: Unlike a mechanical filter that physically removes debris, a biological filter works at a microscopic level. Aerobic beneficial bacteria colonize and flourish on the surface area of filter media – like BioBalls™, mats and the like. As the water passes through the filter media, the bacteria feed on the debris and remove it from the water. Because the beneficial bacteria are living microorganisms, they function best when water temperatures are near or above 50 degrees Fahrenheit when they’re alive and kicking.

You don’t really “clean” a biological filter at all because you want to retain as much of the beneficial bacteria as possible. In the early spring, perform a cleanout and seed with natural bacteria like Microbe-Lift® PL Gel or Pond Logic® Seasonal Defense® to give your filter a fresh start. Throughout the season, do a mild rinse in a bucket of pond water only when the water flow begins to decline. Each time to clean or rinse your filter media, add a dose of Microbe-lift® PL Gel or bacteria from the Pond Logic® DefensePAC® to re-seed the bacteria and replenish any bacteria loss.

Though it may be tempting, don’t power wash or swap out filter media mats. This strips the beneficial bacteria, which may take weeks to replenish! In the meantime, algae will feed on the unfiltered nutrients in the pond water, and you’ll see your water quality diminish as fish waste accumulates – which is something you don’t want!

I’m tired of fighting algae. Will a UV take care of all the algae growth? | Decorative Ponds & Water Gardens Q & A

Q: I’m tired of fighting algae. Will a UV take care of all the algae growth?

Cherice – Everett, GA

A: Who isn’t tired of battling algae!

Caused by excess fish waste and dead organics from leaves or previous algae blooms combined with excessive spring- and summertime sunlight, all that garish green growth looks horrible, ruins your water quality, and creates a headache for you and your fish.

Is an ultraviolet clarifier, like The Pond Guy® PowerUV™ Clarifiers or the AllClear™ PLUS Pressurized Filter the answer? It depends on the type of algae you’re trying to destroy.

Know Your Algae

The algae that forms in your pond comes in two basic flavors: planktonic and filamentous.

  • Planktonic algae, the source of pea soup algae blooms, are floating, microscopic plants that color pond water shades of green, blue-green, brown or variations in between. In controlled amounts, this type of algae can actually be beneficial. It’s considered the start of the pond food chain as the tiny plants feed fish inhabitants, and it can also shade the pond’s bottom, preventing subsurface nuisance plants from growing. In uncontrolled amounts, however, planktonic algae can cause oxygen depletions and fish kill.
  • Filamentous (string) algae are single-celled plants that form long, visible chain, threads or filaments. These threads, which start growing along the bottom of the pond in shallow water or on rocks or other aquatic plants, intertwine and form mats that resemble wet wool. When these mats rise to the surface, they’re commonly referred to as pond scum. These mats make great homes for micro- and macro-invertebrates, like bugs and worms, but they’re also unsightly.

UV clarifiers work by destroying the ultrafine planktonic algae – but, unfortunately, they do nothing to combat the filamentous algae. You’ll need a different strategy for the stringy stuff.

Battling Planktonic Algae

So how does ultraviolet light fight planktonic algae? When the algae cells are exposed to the bulb’s ultraviolet rays, radiation destroys the plants’ cellular walls. As a result, the tiny particles of dead algae clump together, and those clumps are then removed by your mechanical filtration system.

For the UV clarifier to work properly, however, follow these guidelines:

  • Replace bulbs yearly. Worn-out bulbs – even if they still light up – may not be as effective at controlling green water.
  • Watch your flow rate. Pushing water past the UV too fast can damage the unit and not allow enough contact time with the UV bulb for it to be effective.
  • Don’t flow too slow. Running a UV at too slow of a flow will act as a sterilizer and may also have a negative affect on natural bacteria meant to help decompose dead organics and fish waste.

Finding Balance

If you have an algae problem, be it planktonic or filamentous, it indicates your pond is out of balance. An ultraviolet clarifier should actually be one of your last tactics! Add some beneficial bacteria from the Pond Logic® DefensePAC® Pond Care Package to help reduce the amount of organics in your pond. Start aerating the water. Consider using pond dye. If you have a thriving fish population, think about finding a new home for them (but don’t release them into the wild!). Manage the nutrients, sunlight and oxygen levels, and your algae proliferation should naturally level out on its own.

Beth – Hinesville, GA

A: Round, oblong, square, kidney-shaped, oval or otherwise, ponds come in all shapes and sizes. In most cases, they’re designed to fit into and enhance their environment. But does shape matter? Read on to learn more.

Tried-and-True Standards

Many ponds are curved and centered toward the viewing area – and there’s a good reason for that. An oval- or kidney-shaped pond allows you to see more of your water garden from one place. Imagine sitting on your deck or patio and enjoying a 180-degree view of your natural-looking waterscape. When compared to a perfectly round or square pond in the middle of your yard, you can see why one might have more aesthetic appeal than another.

Oval- or kidney-shaped ponds also allow for optimum circulation, particularly when a RapidFlo™ Ecosystem Pond Kit or AllClear™ Ecosystem Pond Kit is installed. A waterfall located at one end of a slightly curved pond will gently push the water toward your skimmer or pump for circulation and filtration. Round ponds or those with many coves or inlets may have areas of little circulation, which will require extra waterfalls, fountains or pumps to move the water and prevent it from stagnating.

Outside the Oval

Of course, if you want to play with pond shapes and design a waterscape that’s outside the ordinary, have at it! A rectangular pond teeming with colorful koi could be a stunning centerpiece in a modern-themed yard. A haphazardly shaped pond outlined with irises and arrowhead could transform a suburban postage-stamp yard into a natural wonderland. Just be sure you provide adequate aeration to all its corners and coves.

Regardless of its shape or size, a koi pond or water garden will make a valuable addition to your yard. Check out magazines for inspiration. Pin favorites on Pinterest. Sketch out your ideas. When you’re ready, talk to one of our pond design experts – and get ready to start digging!

I’ve used lava rock in my filter for years. Are bioballs really that much better? | Decorative Ponds & Water Gardens Q & A

Q: I’ve used lava rock in my filter for years. Are bioballs really that much better?

Q: I’ve used lava rock in my filter for years. Are bioballs really that much better?

Dana – Altadena, CA

A: The media you use in your filtration system matters. Just think about its purpose: To house billions of beneficial bacteria and other microorganisms that keep your pond alive, crystal clear and algae-free. Thanks to their ample surface area, both lava rock and bioballs will work, but bioballs have some benefits over the rock. Read on to learn more.

Lava Rock’s Limitations

Lava rock – that igneous rock that’s formed as an erupting volcano’s molten lava cools and hardens – is very porous. When chunks of it live in your filtration system, you’re providing a lot of surface area for those beneficial bacteria to colonize and grow. That’s what makes it such a great filter media.

It does, however, have its drawbacks.

  • Clogged Holes: Over time, the porous rock can become easily clogged with muck and debris. Once the holes and pockets are clogged, they can become very difficult to clean out – which ultimately creates less overall surface area.
  • Hard Water: Lava rock naturally contains a variety of minerals, including iron and magnesium, that could affect your water’s pH, making it harder. Hard water could make it more difficult to treat algae that forms.
  • It’s Heavy!: They may be porous chunks of rock, but hefting bags of it takes some strength – particularly when its wet and full of gunk.

Benefits of BioBalls

Bioballs, like The Pond Guy® BioBalls™ filter media, are plastic spheres made up of dozens of thin rods that provide plenty of surface area for beneficial bacteria to thrive. Two hundred of the bioballs in a mesh bag will filter about 1,000 gallons of water in a pond with minimal fish.

Compared to lava rock, bioballs have some definite benefits.

  • Easy to Clean: Bioballs can also become clogged, by they’re easy to clean. Just rinse them off with water from your pond and you’ll be good to go.
  • Indefinite Lifetime: Because they’re made from long-lasting material, bioballs will not degrade and will function equally well year after year.
  • Shape Shifters: The bioballs’ round shape allows them to more easily conform to any filter, no matter its shape.
  • Lightweight, Easy to Handle: Each one of these tiny, 1 1/2-inch plastic spheres weighs a scant 0.3 ounces; 200 of them weigh a whopping 3 1/2 pounds. They’re easy to deposit and remove from your filter thanks to a mesh filter bag.

Consider making the switch from lava rock to bioballs. You’ll see better results and you’ll need to do less maintenance. What’s better than that?

What does it mean when you say a pond must “cycle” before adding fish? | Decorative Ponds & Water Gardens Q & A

Q: What does it mean when you say a pond must “cycle” before adding fish?

Q: What does it mean when you say a pond must “cycle” before adding fish?

Sherry – Raleigh, NC

A: The term “cycle” refers to the nitrogen cycle – and it’s an important process to understand if you plan to keep fish in your pond. The nitrogen cycle provides the biological filtration in the water, which keeps the water free from toxic compounds created by decaying organic matter. The process is a complicated one, so here are the basics.

Nitrogen Cycle 101

Before we discuss cycling a new pond, let’s dive into how the nitrogen cycle looks in an established, mature pond. As organic material – like uneaten food, dead plant matter and fish waste – decay, the bacteria that break it down release ammonia, which is toxic to living organisms. One particular microorganism called nitrosomonas, however, loves ammonia. It feeds on ammonia and oxygen, and releases a chemical called nitrite.

Nitrites are also dangerous to fish and aquatic critters, and so another group of microorganisms – nitrobacter – enters the nitrogen cycle picture. These bacteria transform nitrites into relatively harmless nitrates, which are then absorbed by algae and plants or reduced by water changes.

New Pond, New Bacteria

A new pond doesn’t have healthy populations of nitrosomonas and nitrobacter yet, and so the pond must be “cycled.” This refers to establishing and maturing your pond’s biological filtration system so that it’s able to turn ammonia into nitrates. To do so, you need to start the process with an ammonia source (a few hardy fish) and seed the pond with these beneficial bacteria, which can be found in Pond Logic® Seasonal Defense® and in Microbe-Lift® PL Gel.

Nurturing Nitrosomonas

In the early spring when established ponds are waking up after a long winter, a similar cycling process will take place. Some nitrosomonas and nitrobacter will survive in your filtration media and gravel and begin to colonize, but it’s a good idea to give them a boost. Pond Logic® Seasonal Defense® is formulated for use in cooler temperatures – making it perfect for early spring applications. Since those microorganisms live in your filtration media, avoid washing it when you’re doing your spring cleaning.

Cycled and Ready for Fish

The cycling process can take four to six weeks, though in the warmer spring and summer this time may be reduced. Keep an eye on your ammonia, nitrite and nitrate levels with a test kit, like our PondCare® Master Liquid Test Kit. Once it indicates that nitrates are present, your pond is considered cycled. Add only a few fish at a time to prevent ammonia levels from spiking again.

Keep in mind that this ammonia-nitrite-nitrate cycle is always occurring, so test your pond regularly to ensure the health and wellbeing of your finned friends.

Q: I want to upgrade my filtration system. What are my options?

Brock – Baton Rouge, LA

A: In just about every pond keeper’s life, the time comes when they want (or need) to upgrade their filtration system. Whether they’re looking for a filter that will handle a higher fish load, a three-in-one system that has UV light built right in, or one that’ll efficiently skim out leaves falling from that overgrown maple tree, a new filtration system can improve water quality – and give hobbyists a fun new water garden gadget to play with.

Ready to check out some options? Below, we’ve outlined several upgrade choices for your pond filtration system.

  • In-Pond Filtration Systems: The ClearSolution™ 4-in-1 Pond Filtration System is an ideal upgrade for ponds 1,200 gallons or less, particularly if the existing filter is a waterfall filter box. This unit uses mechanical and biological filtration media to remove large debris and dissolved organics, while a powerful ultraviolet clarifier clears discolored water. The system also features a compact energy-efficient mag-drive pump, which circulates water through the filtration system and discharges it through a fountain head attachment or a diverter valve. You can upgrade your filter and add a fountain!
  • External Pressurized Filters: For those with larger ponds up to 4,800 gallons, the AllClear™ PLUS & SolidFlo™ Combo Kits offer mechanical, biological and ultraviolet filtration in an efficient, economical filtration unit – but it also includes a back-flush system that allows you to clean the filter with the turn of a dial and rinse away waste water and debris via a discharge outlet. The AllClear™ PLUS system with SolidFlo™ Solid Handling Pump is great upgrade for existing ponds with high fish populations.
  • Waterfall Filter Boxes: Add a water feature to your pond while stepping up your filtration with a waterfall filter box, like the ClearSpring™ Waterfall Filter. The unit houses Bio-Balls and two filter pads of varying density for maximum filtration. For the waterfall pattern, you can choose between two included weir options – a traditional smooth sheet-like surface and a ribbed pattern. You can even plumb multiple boxes together via FPT inlets located on both sides of the waterfall box.
  • Skimmer Boxes: A skimmer is a practical upgrade in ponds with a lot of leaves. If your pond requires a high-volume pump that you want to hide, or if you want to add some extra mechanical filtration, check out the TetraPond® In-Pond Skimmer. This unit includes a large removable debris basket and an automatically adjustable weir door for maximum surface cleaning. And it’s easy to install: Place the skimmer on the bottom of your pond, weigh it down with gravel, connect it to your pump and let the skimming begin!

A new filtration system is a great investment in your hobby. Whichever you choose, have fun and enjoy the upgrade!

Can you add too much beneficial bacteria to your pond? | Decorative Ponds & Water Gardens Q & A

Q: Can you add too much beneficial bacteria to your pond?

Q: Can you add too much beneficial bacteria to your pond?

Michelle – Norman, OK

A: They say too much of anything is bad. In this case, too much beneficial bacteria isn’t necessarily bad – but your pocketbook might be getting a little lighter.

The Cycle of Life

Beneficial bacteria, those debris-gobbling microorganisms found in our Nature’s Defense®, Muck Defense® and Seasonal Defense®, lives just like other living things. They’re born (well, most bacteria come into the world via a kind of cellular division called binary fission), they eat food that’s available to them (organic debris in your pond), they divide to perpetuate the population, and they die when their life cycle is complete.

Survival of the Fittest

When too many bacteria live in your water feature, they battle and compete for resources rather than growing big and healthy and reproducing. A la Charles Darwin’s theory of natural selection, the weaker organisms ultimately starve and die. The overall bacteria populations drop, and the pond owner then needs to buy more to replace what he or she has lost to keep up on managing the nutrient load. Those repopulation costs could certainly add up over a while!

Too Much of a Good Thing

Having too much beneficial bacteria in your pond is safe for plants and fish in most cases. But if your pond has a lot of organic buildup, a lot of beneficial bacteria and inadequate aeration, could be a recipe for disaster for your fish. As those bacteria launch their full-scale attack against all that detritus, they deplete the water of oxygen – which the fish needs to survive. An aeration system, like the PondAir™ or KoiAir™Aeration Systems, can help in cases like that by supplying the oxygen and circulating the water column.

The Right Dose

Our advice: For routine maintenance, dose your pond according to the instructions on Nature’s Defense®, Muck Defense® and Seasonal Defense® labels. After clean-outs or treatments, you can use a double dose of bacteria to kick-start the repopulation process, but no more than that. And, if you don’t have one installed already, consider adding aeration to your pond. All your pond’s inhabitants – from microorganism to macro organisms – will appreciate it!
