SURFACE SKIMMER
Ista’s Surface Skimmer prevents dust and protein layer formation. This layer can filter the light that reaches the plant and gives an awful aspect to the aquarium. 
CHARACTERISTICS:
-Effectively draws the dust and protein to the skimmer which assures a crystal clear water surface.This creates a healthier and safer environment， as it allows effective gas exchange and proper light for plants.
-Allows surface water flow to get through from all directions without clogging.
-With self-floating water inlet chamber， it automatically adjusts itself with the change of water level.
-Works perfectly with hang on filters and other middle size filters.
