Empty filter d70: with 1.1 - 2.7 litres volume

The feed water from the aquarium is pumped into the system by means of a bypass of the main pump or an additional feed pump. With the AquaCare empty filter the following filter techniques can be realized (additional material is required):

1. Submerged downstream operation: the water flows from top to bottom. If a fine filter material is used (e.g. quartz sand, zeolite), the filter can remove particles from the water; however, it must then be rinsed regularly; we recommend filling the filter only to 75% so that there is enough space for backwashing.
   Our recommendation:
   upper sieve:
        15 mm sceens
   bottom sieve:
        15 mm sceens plus filter sponge or
        depending on the fineness of the filter material, screen from 6 µm to 15 mm
   We recommend a vent valve for operation.
    
2. Submerged upstream operation: the water flows from bottom to top. This method is used to be able to use abrasion-sensitive filter materials (e.g. activated carbon, lime materials, simple phosphate adsorbers, sulphur granulate).
   Our recommendation:
   top screen:
        15 mm screen; for fine filter material an additional filter sponge
   bottom screen:
        15 mm screen plus filter sponge for fine material or
        depending on the fineness of the filter material, screen from 6 µm to 15 mm
    
3. Fluidized bed filter = Moving Bed Filter: the water flows from bottom to top at a high speed so that the filter material moves and cannot clog (e.g. quartz sand, zeolite, AquaCare +Globuli, high-performance phosphate adsorbers, bio pellets). The best effect is achieved with a fluidized bed insert. This filter is also available ready-made here in the shop. 
   Our recommendation:
   top screen:
        15 mm screen plus filter sponge
   bottom screen:
        fluidized bed screen and
        for filter material below 3 mm grain size, a non-return valve in the inlet
    
4. Trickling filter = trickle filter: the water flows from top to bottom over filter material - there is an air atmosphere in the filter. An air pump can be connected to the cover connection for more effective oxygen enrichment. A trickling filter insert and an additional connection (e.g. valve) are required. This filter is also available ready-made here in the shop. 
   Our recommendation:
   top screen:
        4 mm or 8 mm screen
   bottom screen:
        depending on filter material size inserts from 15 mm to 4 mm
   We recommend a vent valve for operation.
    
5. Gas filter: the flow is from bottom to top. These filters are also available ready made here in the shop.
   Our recommendation:
   for CO₂-X-Globuli ("soda lime") oder H₂O-X-Globuli (drying perls):
   upper and lower sieve: 2 mm screen
   an O-ring for the central tube and a silicone buffer for the upper strainer are additionally required
    
6. Special filters: with the appropriate sieves and partly circulation pumps, the following systems can be built from the empty filter. These filters are also available in the shop ready-made:
   OZR = ozone reactor, KWR = lime water reactor, ADN = sulphur-based nitrate filter
    
7. Resin filter: the flow is from bottom to top. These filters are also available ready made here in the shop.
   Our recommendation:
   upper and lower sieve: 200 µm screen
   an O-ring for the central tube and a silicone buffer for the upper strainer are additionally required
