ECO Mini 28R Aquarium

Eco Mini 28r Front Eco Mini 28R Back


“Of all the nano aquariums I have set up and maintained, the ECO MINI is the best! The fan, as well as the open top, means heat is not an issue, as it is in the traditional “hotbox” we are so used too in most nano aquarium designs.”

Scott Michael, Author of Reef Fishes Series

The ECO MINI 28R nano aquarium incorporates the EcoSystem Miracle Mud Method in a superior-quality, built-in filtration system. This unique filtration system ensures that the reef animals housed in the aquarium have the best chance to thrive long term. The EcoSystem Method has three distinct functions:

  1. It is the most efficient denitrifying filter (fixes/eliminates nitrate in the aquarium);
  2. Miracle Mud continuously replenishes the mineral and trace element concentration in the aquarium, making this the most comprehensive filter available (you do not need add any supplements to this nano aquarium);
  3. The built-in refugium provides a continuous micro food-web for your nano reef inhabitants (no need to add phytoplankton/green water to this nano aquarium).

In addition, the ECO MINI 28R has a phosphate-removing component built in, to keep this nano aquarium free of nuisance algae and/or cyanobacteria (red slime algae).
