**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.

 Biotec 4 is the smallest filter in this range. It is a 4-stage filter. The UVC clarifier Bitron 9 is available as an accessory and can be simply installed inside the filter without the need for any other accessories.

Biotec 5.1 and Biotec 10.1

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 15 to 72 UV clarifiers and a Aquamax or Promax pump  is possible without the need for any further parts.

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 Münster-based company BIOLOGIC Gesellschaft für Biotechnologie 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.
