Frequently Asked Questions

After a filtration system has been installed, how long does it take for the filter bacteria to build up?

Usually it takes between 4 and 6 weeks until the filter bacteria have established themselves in sufficient quantities. We recommend only turning the Bitron on after that time.

To shorten the start-up time of the filter, we recommend using OASE Biokick. Biokick has micro-organisms that have been grown in the laboratory and multiply at a water temperature greater than 10°. These micro-organisms are needed for biological filtering in the garden pond. Adding these strains shortens the start-up time.

The bacteria are active at app. 10 – 12 degrees. The higher the temperatures the better the biological filtration.
