Pond Filtration

Specifically, the new Biotec filters have an individual chamber, which is filled as standard with Zeolite, However, as the name indicates, the use of other filter media such as Oase Phosless is possible.

The Biotec filters are "activated" with the aid of the Teichkur set, consisting of strains of bacteria, special granules and a bio-stabilizer.
 
This results in the colonization of friendly bacteria which get rid of harmful substances by converting ammonia into nitrite, nitrite into nitrate and nitrate into nitrogen, which then volatilizes and is therefore removed from the pond.

The Biotec 5 is designed to eliminate cloudy, dirty water and algae growth by converting ammonia, produced by fish waste, dead plants, etc., into nitrite and then into relatively harmless nitrate using a natural process. This filter is designed to be used outside of the pond and cannot be pressurized.

The Biotec 5 contains a temperature indicator and a pollution indicator to indicate bacteria activity and show when maintenance is necessary. 

During the past few years OASE has with Biotec 5 and 10 marketed the most successful filter concept available.

Biotec 5.1 and Biotec 10.1 are the direct follow-up developments of these great products.

Basically, these new filters are also flow though filters which have many advantages such as the rich supply of oxygen and high flow through rates.

Remaining fish food, fish excrement, dead plants and also petals, leaves and dust brought in by the wind pollute a pond with a surplus of nutrients. The closed system of a pond with liner or pre-formed ponds allows only a limited amount of nutrient exchange and decomposition. The consequences are often algae growth and murky ponds. Increased decomposition processes also pollute the pond with toxic substances, which will reduce plant growth and endanger the health of fish or other occupants of the pond.

The biological cleaning
This is where Biotec 5.1 and Biotec 10.1 get really active. The polluted water is fed into the filter system with the help of an Aquamax filter pump. The optimised filter surfaces trap the pollution particles and thus clean the pond mechanically. Additionally, the filter develops the all important biological environment to enable the nitrification in oxygen-rich conditions (blue and red filter foams). During this process toxic nitrite compounds are converted into other harmless compounds.

The Biotec 10.1 system is the follow-up to the successful Biotec 10 model. This new model is also a flow though filter which have many advantages such as the rich supply of oxygen and high flow through rates.

The polluted water is fed into the filtration system with the help of an Aquamax pump. The filter surfaces trap the particles and organic debris, cleaning the pond mechanically. Also, the filter develops an active biological environment to enable the nitrification in oxygen-rich conditions. During this process toxic nitrite compounds are converted into other harmless compounds.

Cleaning just became easier with the Biotec 10.1 also. When filter foam requires cleaning they may be squeezed against an intermediate plate with a new cleaning lever. The waste outlet can then be opened, allowing the dirty water to drain out.

Simple operation, fast, clean maintenance, and an outstanding filtration result are the unique features of the Biotec 12, 18 and 36 range.

A specially designed screen retains all particles up to 100 microns. After the water flows through a special mat where it is enriched with oxygen flowing then into the filter zones
