ZollaBox Clear Water XL: natural solution against green water (large aquariums and ponds)

What is the ZollaBox Clear Water XL?

It is a large-format green water control kit based on the plankton food chain: you protect daphnia inside the Zolla'Clear XL so they filter the microalgae responsible for green water. This way, they can work safely away from the fish's appetite. Chemical-free, reusable with refills, and delivered with live daphnia, a net, and instructions. Aquazolla innovation (2019).

Suitable for ponds or aquariums of 300 liters and above.

Why use the ZollaBox Clear Water XL in a natural aquarium or pond?

  • Eliminates green water naturally: daphnia filter the suspended algae that give the water its green color.
  • Respects the balance of your ecosystem: zero chemical products, no microbial "shock." Indeed, killing suspended algae is dangerous.
  • Turns a problem into a resource: algae feed the daphnia, which in turn provide live food for the fish. Green water ultimately feeds the fish!
  • Ecological, economical, and reusable: carefully store the Zolla'Clear XL after use and restart with a simple daphnia refill if needed.
  • Simple and educational: show the plankton chain "for real."

Who is the ZollaBox Clear Water XL for?

  • Aquarists facing green water in aquariums over 300 liters or in ponds.
  • Natural ponds and aquariums of 300 liters and above.
  • People seeking a biological approach rather than using sometimes dangerous biocidal products.
  • Educational projects (plankton cycle, ecological balance).

Introduction and usage tips

  • Install the Zolla'Clear XL in the tank or pond and introduce the provided daphnia.
  • If needed (too restless fish, current...), attach it to a support (glass, wire, stake, sturdy plant stem...) with a clip, for example.
  • Let it act: the daphnia gradually filter the green water until it becomes clear again. They reproduce, the older ones die and lay the next generation.
  • The time needed varies depending on the intensity of the green water, volume, number of daphnia, temperature, light, etc. Generally between a few days and several weeks.
  • Close the loop: once the water is clear again, collect daphnia to feed the fish.
  • Reuse: store the Zolla'Clear XL. In case of recurrence, order only the ZollaBox Clear Water XL refill (new daphnia) and start again.

FAQ - ZollaBox Clear Water XL

How long does it take for the water to become clear again?

Depending on the algae density and volume, improvement is gradual: the daphnia work continuously until the water becomes clear again. Usually, it takes a few weeks, sometimes less.

Do the daphnia survive with the fish?

They are protected inside the Zolla'Clear XL. Outside the device, fish eat them (this is intended to close the chain at the end). If the fish are too lively and restless, simply secure the Zolla'Clear XL with a simple clip (like a clothespin...) to a solid fixed point (glass, sturdy plant stem...). This way, they won’t be able to overturn it!

Can the box be reused?

Yes: it is reusable. Store it carefully after use, and simply get a refill to add daphnia if it needs to be used again.

Difference from a chemical anti-algae product?

No toxicity, no microbial imbalance, and no water changes because a mass of algae was killed at once. This is the biological way. Algae are transformed into live daphnia, not into dead waste that heavily pollutes the aquarium. No plants suffer.

Does it also work in ponds?

Yes, the planktonic logic applies in aquariums as well as in ponds.
