JEBO aquarium 520 Skimmer improves skimming efficiency and gas exchange with
venturi action. Water and air swirl together to producing abundant mini air
bubbles in the vortex chamber, rapidly drawing out dissolved wastes.
Bubble foam is collected in a top mounted collection cup. Very easy to use
and maintain. Ideal skimmer for both new and experienced marine aquarists. 520
skimmer completes with a powerful AP5200 power head.
