Tips & Tricks

The conical body of the ARKA® Core skimmer, the advanced bubble chamber and conical diffusers work in synergy to mix air and water with the highest efficiency.

The special design eliminates turbulent flows and swirls that would affect performance. The diffusers enable a stable laminar flow in the reaction chamber, which leads to unprecedented skimmer performance and efficiency. The hybrid cone design maximises the reaction chamber size and thus facilitates efficient removal of harmful substances. The innovative bubble chamber reduces turbulences to a minimum and generates a stable laminar flow, which enhances bubble transfer and increases skimming performance.

The innovative bubble chamber combined with the powerful, high-quality needle wheel pump generates ideal air bubbles that guide proteins and other waste substances rapidly and efficiently through the cone body into the collection container.


high-quality pumps Made in Italy

The needle wheel pumps manufactured by Sicce and optimised by us guarantee high air output and balanced bubble action to reliably remove proteins and organic substances from the aquarium. Maintenance is reduced to a minimum to leave you with more time for your aquarium.

A reef in your living room – a low-noise backdrop 
The ARKA® Core Skimmers were developed from the ground up for use in living rooms. A built-in air inlet silencer reduces noises for almost silent operation. Rubber feet insulate noises and reduce vibrations.
