Thank you for looking.
This product makes aquarium maintenance much easier.

Two installation patterns are possible: suction type and upward flow type.
Increases filtration area and helps maintain water quality.
Water flow keeps the substrate in an aerobic state at all times.
Prevents the generation of hydrogen sulfide due to the accumulation of organic deposits.
Effective for planted aquariums that require gentle water flow around the roots, and for large fish that produce a lot of waste.
*Please use substrate with a diameter of 3mm to 5mm. If using soil, the water may become cloudy. Also, if the soil breaks down, it can clog the bottom plates, putting a load on the motor and increasing operating noise.
