Should I use just one type of filter media or are multiple types better? | Decorative Ponds & Water Gardens Q & A

A:  Filter media—or the stuff in your filter that holds beneficial bacteria—come in a range of shapes, sizes and densities. Some are plastic balls; some are fibrous mats and blocks; some are plastic spiral-shaped things that more resemble fusilli than pond products. With all the different types, it’s tough to decide which is best.

Well, we’ll make it easy for you: Try a little of each type. Just like plants, different filtration media provide different amounts of water filtration, so we recommend a healthy mix of media pads, like Matala® Filter Media Pads, and Filter Media Pads pre-cut and by-the-foot; ridged plastic balls, like The Pond Guy® BioBalls™; and curly plastic strips, like Bacti-Twist® Biological/Mechanical Filter Media.

When choosing the filter media, regardless of type, look for these defining characteristics:

  • Durability: Your media should be able to withstand wear and tear. The Pond Guy® BioBalls™ are more durable and longer lasting compared to similar products.
  • Density: Your media should be the right density for your specific needs. Matala® Filter Media Pads come in 4 densities to suit your particular pond.
  • Surface area: Your media should also have a lot of surface area, which will result in more places for beneficial bacteria to grow.

Your filter media’s density and surface area are particularly important because they determine how much beneficial bacteria grows and the rate at which water flows through the material. Dense material allows for more bacteria colonization, while less-dense material allows for more water flow. By using all different types of filter media, you’re encouraging optimal biological and mechanical filtration—and that’s always a good thing in an enclosed system.

Already have filter media in your system? You may be able to use it for another season or two, but first give it a visual inspection. Is it beginning to wear on the edges? Has it compacted over the last few seasons? Worn or compressed material should be replaced to give your pond top-quality filtration, but fresh, fluffy material can be reused.

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

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 should I do with my filter media during the winter? | Decorative Ponds & Water Gardens Q & A

Barb – Sterling, CO

A: Your pond’s filter media—the Matala® Filter Media Pads, The Pond Guy® BioBalls™ or Bio-Ribbon that house your beneficial bacteria—will need a little attention going into the winter. You won’t need your filter media during the cold months, but you should inspect it, clean it and purchase replacements parts before you start your water feature up again in the spring. Here’s a rundown of what to do:

Filter Media Pads: Pull out your filter media pads from your pond’s filtration system, waterfall box and skimmer, thoroughly rinse off the debris with your garden hose, and look for frayed edges, holes, large deposits of solid debris or other signs of damage. Plan to replace worn pads as necessary in the spring. You can choose from specially coated Matala® Filter Media Pads, which come in four different densities for your unique filtration needs, or cost-effective rolls of filter media that can be cut to fit and are ideal for waterfall boxes and skimmers.

BioBalls and Other Loose Filter Media: If you use secondary filtration, like The Pond Guy® BioBalls™, Bio-Ribbon, blocks or other loose filtration media that’s kept in a mesh bag, remove it all from your filter or waterfall box after you shut down your waterfall, rinse the bag and its contents thoroughly, and check the bag for holes or worn areas. Replace the bag if necessary in the spring.

After your filter media is rinsed and inspected, you can store them for winter in the filter, waterfall box or skimmer. The filter pads, BioBalls™ and other media will survive just fine outside, even in freezing temperatures. If desired, you can also remove them and stow them inside a garage or basement.
