For best suction performance, position the bottom of the waste compartment as close to the tank floor as possible.

In smaller tanks, lower-power models are recommended to avoid excessive water movement that could stress fish.

Frequently Asked Questions

Q: Which model aquarium internal sponge filter should I choose for my tank?

A: Choose based on your tank's water volume. The 800F (4W, 450 L/H) and 801F (6W, 600 L/H) are ideal for small or nano tanks. The 802F–803F suit medium aquariums, while the 805F–807F are designed for large tanks requiring high flow rates up to 3000 L/H. As a general guide, your filter should cycle the total tank water volume at least 4–6 times per hour.

Q: Does this aquarium filter come with water pipes or tubing?

A: No, water pipes or tubing are not included with this sponge filter. You will need to source compatible tubing separately based on your aquarium setup and the outlet size of the model you select.

Q: Why are there fewer bubbles when the filter is placed at the bottom of the tank?

A: This is completely normal. When the filter is positioned deeper in the tank, the increased water pressure and depth can reduce the visible bubble output from the oxygenation function. The filtration and circulation performance are not affected — you can use it with confidence at any depth.

Q: Is this internal sponge filter safe to run continuously?

A: Yes. Models 15W and above (802F–807F) include an anti-dry-burn safety feature, making them suitable for extended continuous operation. Lower-power models (800F, 801F) should be monitored to ensure they remain submerged at all times during use.
