Oxygenators - Good to Know

What is the difference between Bunched Oxygenators and Deep Potted Oxygenators?

Potted oxygenators sit a little higher in the water and often have more varied foliage and leaf shapes, making them brilliant for providing cover for spawning amphibians and shelter for froglets. Some varieties can even form a lovely carpet on the pond floor, adding texture and interest.

Bunched oxygenators, on the other hand, sink right to the bottom with their lead weights and root into the substrate. They release oxygen deep in the water, which is great for keeping your pond fresh and healthy.

You don’t always need both—it depends on your pond’s size and style (and what you fancy). That said, we think they make a great team, each bringing their own benefits to your pond.

How Deep Should I Place My Potted Oxygenators?

The planting depth for potted oxygenators depends on the variety, so it’s always best to check the product page or the care label that comes with your plant. Some are perfect for marginal shelves, while others thrive on the pond floor or a lower shelf.

Keep in mind, planting depth is measured from the top of the pot to the water’s surface - so make sure you’re giving your plant the right conditions to grow!

How Many Potted Oxygenators Do I Need?

  • 1ltr Plants: 5 per linear metre or sqm
  • 2ltr Plants: 3 per linear metre or sqm

Tip: Leave space between plant varieties to prevent dominant species from taking over. For more details, see our Planting Guide.

Do I Need to Line My Basket with Hessian?

No, Finofil aquatic baskets are designed with a fine mesh that prevents soil loss. Adding a liner is optional but not necessary.

What Are Finofil Baskets Made From?

Finofil aquatic baskets are made from 100% recycled plastic and manufactured in the UK. They can be recycled at local recycling centres or through kerbside collections that accept black plastic. Plant labels are also recyclable.

Will Carp or Ducks Eat My Plants?

Carp (inc. Koi): These fish find pond plants irresistible! If you have carp, we recommend protecting your plants with barriers.

Goldfish: Goldfish may nibble on oxygenators and softer plants but generally cause less damage. They also eat insects, larvae, and tadpoles.

Wildfowl: Ducks and other birds may eat plants or damage roots while nesting. Mature plants with strong root systems are more resilient, but consider protecting roots/rhizomes for added security.
