Fluidized Moving Bed Bio Filter for Aquarium with Air Stone
Keep your fish tank crystal clear and your aquatic friends thriving with this Fluidized Moving Bed Bio Filter. Engineered with an upgraded fluidized bed design, this transparent acrylic filter creates a nature-inspired biological filtration system that continuously circulates bio media balls, breaking down organic waste, removing odors, and boosting dissolved oxygen levels — all in one compact unit.
⚠️ Note: An air pump is required for operation (not included). Bio media balls float initially — soak for 1–2 days before use to achieve full tumbling action.
Key Features

Frequently Asked Questions
Q: Does the fluidized moving bed bio filter require a pump to operate?
A: Yes, an air pump is required to drive the fluidized bed filter (pump not included). The pump pushes air through the air stone inside the unit, causing the bio media balls to tumble and roll for effective biological filtration.
Q: Do I need to clean or replace the bio media balls in this aquarium filter?
A: No maintenance is needed for the bio media balls. They self-clean through constant rolling and collision inside the filter chamber, making this a low-maintenance biological filtration solution for your fish tank.
Q: How long does it take for the bio media balls to start tumbling after setup?
A: The bio media balls initially float on the water surface. Soak them for 1–2 days prior to use so they become waterlogged and achieve the tumbling action needed for optimal fluidized bed filtration.
Q: What tank sizes is this moving bed bio filter suitable for?
A: This filter is available in two sizes — 20 cm × 8.5 cm and 30 cm × 8.5 cm — making it suitable for a range of freshwater aquariums. It works especially well in tanks housing fish and shrimp. Install it approximately 5 cm below the water surface for best results.
