The natural vacuum cleaners in the pond

Good to know:

If you put snails, mussels, and moss balls in the pond, they will need a few days to suck up water. After that, they sink to the bottom on their own.

This can take 1-3 days.

Freshwater mussel water conditioner

Bottom cleaner no.1 - Freshwater mussel

Did you know:

  • A freshwater mussel can filter about 10 liters of water per hour? This helps remove pollutants and floating algae.
  • They clean the bottom by consuming bottom silt, dead algae and undigested fish food?
  • Chubs lay their eggs in clams?
  • They can live as long as 80 years?
  • They are most effective when you have 5 to 10 per 1,000 liters of water in the pond?
wall cleaner pond slugs water cleaners

Soil and wall cleaner no.2 - Pond snails

Did you know:

  • Freshwater snails feed on trash, dead leaves, filamentous algae and floating algae?
  • They shun live aquatic plants?
  • They keep the bottom and walls of ponds clean?
  • They prefer to be in ponds from 20 centimeters to about 1 meter deep?
  • They contribute to a healthy ecosystem; snail poop feeds pond plants.
  • They survive the winter if the pond is at least 40 centimeters deep?
  • They function optimally with at least 20 per 1,000 liters of water?
moss ball water conditioner

Soil cleaner no.3 - Marimo moss balls

Did you know:

  • The scientific name for moss balls 'Chladophora Aegagropila' is?
  • They originally come from Japan and are called Mari (bouncy ball) Mo (moss) there? Marimo moss balls symbolize happiness and love.
  • They can withstand extremely hot and cold water?
  • They have a purifying effect, especially when combined with our pond bacteria Bacta Clear, and help remove algae? These bacteria live in the fine hairs of the moss.
  • They function optimally with at least 10 per 1,000 liters of water?
  • They can purify effectively in larger swimming ponds, at larger numbers? (For example, 50 pieces per 1,000 gallons of water)

Frequently asked questions about natural water purifiers

Pond Advice

We always ship our mussels and snails without water. Freshwater mussels and snails can survive on dry land for several days. They always spit out water after packing and then go into dormancy. At our nursery, the pond animals are always in cold water so they are dormant.

When you put mussels and snails in the pond, they are often still at rest. Sometimes this can leave them floating. Fortunately, this is nothing to worry about! Within 3 days these will sink to the bottom by themselves as they absorb water again.

However, always keep in mind the following points to ensure that pond animals feel at home:

  • Enough plants: Having enough plants in the pond will ensure a good biological balance in the pond which is necessary for the mussels and snails to survive. Mainly oxygen plants, water lilies and marsh plants are recommended. This is because oxygen plants provide enough oxygen for the creatures. Water lilies keep the sun out of the pond so the water does not get too warm. Marsh plants are great for snails to hide and the dead leaves are a food source for the animals.
  • Sufficient substrate on the bottom: Provide a layer of about 10cm of substrate. This is not only housing the necessary pond bacteria but this is also where the mussels will burrow.
  • The right depth: We always use a depth for mussels of minimum -40cm and maximum depth of -150cm with a preference for -100cm. This is because not many algae grow at -100cm and the mussels love to eat the algae.

Freshwater mussels

Pond mussels, a species of freshwater mussels, are excellent natural water purifiers in pond ecosystems. These pond mussels are capable of filtering thousands of gallons of water per day, contributing to a clear and healthy aquatic environment. By filtering small particles and algae from the water, pond mussels help improve water quality and keep the ecosystem in balance. Their filtering action is important not only for water purification, but also for maintaining pond biodiversity. Freshwater mussels, like pond mussels, are thus an essential link in maintaining a healthy and vibrant pond life.

Freshwater snails

Freshwater snails, often referred to as pond snails, are an essential part of the aquatic ecosystem and are known for their role as natural water purifiers. These pond snails actually act as a hydrogen purifier by eating algae and organic waste from the soil and plants in the pond. Their presence helps keep the water clear and healthy, making them essential to the balance in many freshwater habitats.
