Using the so-called counter current principle, Sander Power Skimmer (internal) and Model I (external) allow for an intensive skimming process and remove toxic protein compounds.
The big reaction tube provides excellent oxygen enrichment of the aquarium water. The Power Skimmer (internal) and skimmer Model I (external) can be operated with a water pump (injector) or with an air pump and wooden air stones.
