The BioStyle in grey colour by Oase is a modern backpack filter, which is available in three different sizes for aquariums up to 180 l. It does not only catch the eye with its modern and sturdy design but proves itself with many useful features.

Via the filter inlet, which is vertically individualisable, the aquarium water flows towards the filter with a stepplessly adjustable flow rate. The filter is simply attached tot the aquarium wall as a hang-on and secured with variable distance-holders. In the filter chamber, the aquarium water is cleansed through biological as well as mechanical and chemical filtration methods. Biological filterfoam with the strength of 30ppi intercepts coarse dirt particles and, additionally, provides useful nitrifying bacteria with a broad surface for colonisation. Filterfleece cleanses from suspended solids and the carbon cartridge binds chloride and other unwanted chemical substances. This is escpecially useful during the starting phase of an aquarium.


In addition to the holistic filtering process and the varying flow rate from soft to very strong - which also benefits the gas exchange on the water surface - the BioStyle hang-on filter opperates very silently, so nothing disturbs the experience of creating a wonderful underwater scape. A very special bonus, the filter comes with, is its automatic maintanance indicator which alerts when there is the necessity of a cartridge exchange.

The BioStyle hang-on filter is also available in dark-blue colour.

The guarantee period is neither extended nor restarted through guarantee performances; legal guarantee claims do not occur on guarantee performances. If the content of the guarantee is not otherwise specified separately, OASE grants a guarantee in the scope cited below: The prerequisite for claiming any guarantee from OASE, including the extension guarantee is that in the case of parts replacement /repair, the customer must have properly installed original OASE spare parts exclusively for any repair or remediation. Any OASE guarantee is invalidated if products from other manufacturers are used.

We provide guarantee performances, at our discretion, through no charge repair, or no charge delivery of original spare parts or of a replacement device of comparable value.

Reimbursement of expenses for removal and installation, inspection, claims for lost profit and compensation for damages are not covered by the guarantee, nor are more extensive claims for damages and losses, regardless of type, that have been caused by the device or its use.

With regard to intended use, we refer you to the user instructions, compliance with which is the basic prerequisite for a guarantee claim.
