The AquaSkim Gravity from Oase reliably removes surface debris such as pollen and leaves from pond surfaces up to 40m², promoting visibly improved water quality and viewing depth. The AquaSkim Gravity can be flexibly integrated into gravity-fed filter systems and easily connectors to DN110 pipework via the high quality DN160/110 adaptor. Water level differences up to 12cm, caused by rainfall or evaporation are automatically catered for thanks to the floating skimmer section.
