Q & A

The Oase Profiskim 100 skims excess nutrients from the pond surface that can lead to undesired algae growth. The Oase Profiskim 100 offers convincing performance with a large tank volume and enormous flow capacity. Pond skimmers remove solid debris from the surface of the pond water. If protein is in the form of a solid, then it will be collected. If you’re concerned with the level of protein in your pond water, look at specialist skimmers that are designed for protein removal. Why does my pond skimmer not have a plug? That’s what I like about the floating pond skimmers. They are super easy to add to an existing pond. They’re great for preformed ponds and liner ponds, basically, where cutting a hole for a built-in skimmer box is not an option. I also like that you can easily remove or reposition them, something you will likely find yourself doing. For me, I really feel that most people would be happy with either this Oase Swim Skim Skimmer 25 or the larger Oase 50170 SwimSkim 50.

This method of cleaning removes all types of pollutants, including an excess of nutrients so that the water in your pond or pool is beautifully clear and clean. A fine grade sponge performs both mechanical and biological filtration to ensure a thoroughly cleansed pond.

The Oase Swim Skim Skimmer 25 is, for me, one of the best pond skimmers for small to medium-sized ponds. It’s a complete unit because it comes with a built-in pump so it’s easy to set up with nothing else needed. Note that quite a few online reviewers of pond skimmers report that the skimmer starts to fully float when the collection basket is full. This makes the pump run in a dry environment and is not good for the unit. Plus it also makes quite a loud noise. Weir doors and fish

The OASE AquaSkim 40 keeps the water surface of up to 40 m² clean and is an ideal addition to the AquaMax Eco Premium models 8000-16000 and Twin 20/30000. The skimmer basket has a diameter of 170 mm. It can be easily adapted to the pond depth thanks to the two-part telescopic tube, which is infinitely height-adjustable from 300 to 800 mm. The skimmer compensates for water level differences of up to 120 mm. The filter basket volume is 1.4 l. The skimmer lets through dirt particles up to 10 mm in size. Thanks to the 350 mm base, the AquaSkim 40 can be fixed to the pond floor with stones that are particularly stable. The small pipe diameter of 80 mm also ensures less air content and thus prevents the skimmer, which has a connection with a universal stepped hose nozzle from ¾ “to 1½”.

These organic materials decay over time as they sink to the bottom of the pond. Decaying matter produces ammonia which harms the health of your pond’s ecosystem. With the SwimSkim 25 the integrated whirlpool function, if desired, whirls up deposits on the floor of the pond and feeds them to the pump. Both models additionally enrich the water with vital oxygen and thus improve the water quality. The integrated “green” as Oase calls it function, brings up debris from the bottom of the pond by swirling the water at 600L/hr. This causes the light organic matter to come up to the surface of the water where it’s pulled in by the skimmer in the usual way. Additionally, the debris still on the surface of the pond is captured. CrystalSkim 350 is suitable for fresh and marine aquariums up to 92 gallons (350 l).CrystalSkim 600 is suitable for fresh and marine aquariums up to 160 gallons (600 l). Leaves, pollen and other algae nutrients get into the pond water via the surface. Oase skimmers powerfully and effectively extract these dirt particles from the surface, collecting them in the basket. That way, dirt can be removed from the pond ecosystem before it starts to pollute it.

Oase CrystalSkim is designed with a floating ring that adjusts to the water level. It can handle long maintenance intervals without having to top up the water offering cleanliness over a long period of time. The integrated basket offers additional safety for your aquarium inhabitants.
