Oase Living water - Logo - Creative PumpsOase Biotec Gravity Filters (Biological & Mechanical)

Oase Biotec Gravity pond filters are made in Germany. There is models to suit most pond sizes. The biotec range of pond gravity filters are ideal for Koi fish and turtles as they can handle the large amounts of waste that these can produce. The multi type of filter foams help to produce several different types of bacteria to help break down the bad pathogens that can live in the pond water.
The larger filters have filtering screens which cycle every 30 minutes, this screen helps to catch the large pieces of sludge which are sucked up and circulated around the filtration system. The pond filters can suit ponds up to a size of 140,000 litres. You can also add a UVC light to the front of the filters.

Aussie says
Superior quality - Aussie loves this gear!

Aussie's observations

Suitable for: Any pond filtration, Ideal for Koi, turtles and large ponds requiring large scale filtration. Ideal for ponds up to 140,000 litres in size.
What we liked: Quality is second to none, Features are also great, the screenmatics operate every 30 minutes, they clear away any large clumps of algae and waste to a collection basket.
Possible drawbacks: They take up a large area, they do not have a UV clarifier within the filter, but the benefit is that you can put a larger UV clarifier into the filter than what would be standard.
Other filters of this type: Blagdon Midipond

**Special note, if using a waterfall or a long hose between pump and filter the pump will need to be larger to allow for the reduced flow caused by the head (pumping height, and/or hose length)   If in doubt Fill in one of our e-mail help forms and let us do all the calculations for you.
About Biotec filters
The patented silt disposal system allows quick and easy cleaning of the filter and ensures if used correctly the continued development of micro-organisms.

These filters are generally pump fed filters and multi chamber filters, which do not only mechanically filter out dirt from the pond water but also encourage the colonisation of special micro-organisms for the biological filtration process.

Biotec was scientifically developed and tested, and guarantees that if used according to the instructions and in round the clock operation, crystal clear and biologically sound pond water.

Bio Smart 30000 is the smallest filter in this range. It is a 4-stage filter. The UVC clarifier Bitron 24C  is available as an accessory and can be simply installed inside the filter without the need for any other accessories.

Biotec 12, 18 & 36

Biotec 30 is an innovative development for large ponds with Koi. With Biotec 30 and its integrated drain, the facility to remove filtered particles and the biological decomposition of superfluous nutrients. Oase has once again achieved a superior technological lead in the market. This multi-chamber filter features, apart from the brush chamber, an innovative woven mat which increases the extraction of large dirt particles and thereby makes the work for the micro organisms in the later stages of the filtration process easier. The connection to Bitron 24 to 72 UV clarifiers and a Aquamax pump  is possible without the need for any further parts.

Oase Biosys - Based on science
Oase product information
   
Only on the basis of independent scientific evidence can our aim of offering the optimum product be guaranteed. On behalf of OASE-PUMPEN GmbH, the Munster-based company BIOLOGIC Gesellschaft fur Biotechnology und Umweltschutz mbH & Co.KG drew up scientific studies looking at the biological principles and providing assessments of filter pumps, UV-prefilters and filter units.

BIOLOGIC explains the fundamental principles of the interaction in the nutrient balance of a garden pond and finally applies these in relation to the Biotec filters. For more detailed information please read the online version.
 

Furthermore, an assessment system was drawn up, which was used to test the efficiency and performance of OASE filter pumps, UV-pre-filters and filter units.
