This undergravel filter suits aquarium keepers who want biological and mechanical filtration through the substrate. The water is drawn through the bed of sand, active substrate or a natural mix such as ECO PLANT, so the filter works with the substrate you already use. The grid is assembled from separate modules, so the footprint can be matched to a specific tank rather than to a fixed size.
Why it matters
- The filter draws water through the substrate, where organic and inorganic waste is trapped and the substrate is kept clean of fish waste and plant debris.
- The grid consists of twelve individual 14 x 7 cm elements that connect to each other, and they can also be joined at right angles.
- Surplus connectors can be cut off after assembly, allowing the grid to be trimmed to exact dimensions.
- The telescopic outlet adjusts from 30 to 50 cm in height and its nozzle rotates 360 degrees, so the water outflow can be directed as needed.

What it works with
The filter is intended for aquariums with a substrate layer on the bottom, including planted tanks that use sand, active substrate or a natural mix. Because the grid can be trimmed and rearranged, it can be fitted to tanks of different bottom sizes. Water movement is generated by connecting an air pump to the air line, which is inserted into the outlet tube.

Frequently asked questions
The set includes 12 grid pieces, each measuring 14x7 cm, a telescopic water outlet tube, and an air tube with an air stone. An air pump is not included.
Yes, the filter works with a substrate such as sand, active substrate, or a natural mix like ECO PLANT. Water is drawn down through this layer, which keeps it clean of waste such as fish waste and plant debris.
Yes, the air pump is sold separately. Connecting it to the air tube forces water movement through the filter, so the pump is what drives the flow.
The grid pieces connect to each other and can be placed in a perpendicular arrangement as well. Once assembled, you can cut off any extra connectors to get the exact dimensions you need.
The telescopic outlet adjusts from 30 to 50 cm in height, and its tip rotates a full 360 degrees. The price is 29.99 zł gross.
