The AeroTwin L is an internal sponge filter for aquarists keeping small to medium tanks in the 60–120 l range. It addresses the routine of cleaning the filter without taking the whole unit apart, and it lets the keeper adjust the outlet and sponge placement to suit the stock.
Why it matters
- Two independent sponges: one sponge can be cleaned while the other keeps filtering, so the unit does not need to be dismantled for routine maintenance.
- Microporous sponge: the fine pore structure is suitable for fresh shrimp fry.
- Adjustable placement: the sponges can be set vertically, horizontally, or at different heights, and the intake draws water from several zones of the tank.
- Telescopic outlet: the outlet can direct flow below the surface or above the water line for surface aeration, and a separate air tube can be connected for additional oxygenation.
Specifications
- Power consumption: 3 W
- Flow rate: 350 l/h
- Suitable aquarium volume: 60–120 l
- Dimensions: 220 x 65 x 280 mm (height depends on how far the telescopic outlet tube is extended and on sponge setup)
- Weight: 1 kg
What it works with
The filter is matched to 60–120 l aquariums, where its 350 l/h flow and sponge-based mechanical and biological filtration apply. Setting the sponges at different heights or angles helps capture debris across the water column in tanks with heavier bioload. Connect the air tube only when the stock requires extra oxygen.

Frequently asked questions
It is designed for aquariums from 60 to 120 litres. Its rated flow is 350 l/h, and it draws 3 W.
One of the sponges is microporous and suitable for freshly hatched shrimp. You can set the sponges vertically, horizontally, or at different heights in the tank.
No, the filter has two independent sponges, so you can clean one without disassembling the whole unit. Rinse the sponges in water drained from the aquarium to preserve the beneficial filter bacteria.
The telescopic outlet can be placed above the water surface to aerate the water naturally, or below it to direct the flow. You can also connect an extra air tube if the fish stock needs more oxygen.
A drop in water flow usually means one of the sponges needs rinsing. Check the flow regularly, since the filter's flow rate is 350 l/h.
