Description
The Hygger moving bed biofilter works on the principle of fluidization. Fluidization is the process of creating a dynamic suspension, the so-called fluidized bed. The fluidized bed consists of solid particles, in this case a filter bed, moving in a stream of air and water from bottom to top. Fluidization intensifies physical and chemical processes. The phenomenon of fluidization is used in the Hygger biofilter.
Filter contains a filter bed with a large specific surface on which nitrifying bacteria grow. The bed provides the maximum surface area for the growth of these beneficial bacteria, supporting the nitrification cycle. Nitrification is an aerobic process and requires the presence of oxygen to proceed. Very intensive aeration significantly increases the oxygen saturation inside the filter and thus intensifies the nitrification process.

How to properly start the filter:
The biofilter is designed for tanks with a capacity of 30 l to 150 l. The biofilter should be treated as a supplement to the filtration in the tank based, for example, on a biochemical sponge-ceramic filter by Hygger.
1. Before the first use, rinse the filter preferably in RO or water
in the water from the tank.
2. Attach the four suction cups, press them down.
3. Connect the tube to the filter with air supply. The filter is ready for use.
4. Place the filter in the tank. Attention! When the filter is activated for the first time, even bed movement begins after a few or several hours. Patience …
ATTENTION!
The filter must be connected to an appropriately sized air pump. Recommended pump power is 5W.
Be sure to include a check valve on the air supply tubing to prevent water backflow during the power failure.
The filter sponge in the bottom filter cover has a density of approximately 40-45 ppi. It is safe for small and newborn shrimps. Requires regular cleaning every 1-2 weeks.
