-Japanese breeders use these Japanese aeration rings for their koi ponds to prevent dangerous oxygen depletion in both summer and winter. They can also be used for aquariums. -No additional weights are needed as they are self-sinking, ensuring no risk of injury to the fish/koi. -They provide excellent dispersion of air bubbles due to low internal resistance, resulting in minimal clogging or wear. -With a 0.2'' thick hose, they are highly durable and long-lasting. Additionally, all models come with an extra 16.5FT air hose measuring 0.3''. -These rings are ideal for providing aeration in filter chambers and for use in fluidized and moving bed reactors. CESFRE Aeration Ring for All Ponds

To ensure the well-being of your fish, especially Koi, you need to maintain an elevated oxygen
level in your water. Oxygen helps convert ammonia to nitrite and nitrite to nitrate, facilitating
the biological breakdown process. Our self-sinking XRMXF Aeration Ring makes achieving this
easy. The high-quality hose (inner diameter 10mm, outer diameter 16mm) sinks to the bottom
of the pond due to its own weight. Its rounded shape, available in various sizes (depending on
the pond dimensions), also makes it suitable for use in different filter chambers and fluidized
or moving bed reactors.

Application of our CESFRE Aeration Ring for All Ponds and Aquariums

Before submerging the self-sinking aeration ring in the pond, consider the hose length and
the air volume provided by your air pump. It's recommended to deliver an air output of 45-80
liters per hour per meter. Since the ring remains on the pond floor during operation, there's
no need for additional weighting, minimizing the risk of injury to fish or Koi due to attachments, etc.
The fine bubbling effect generated by the ring is beneficial for water mixing in the pond.
