Nicrew Mini Internal Aquarium Filter

If you are dealing with cloudy water or weak circulation in a small aquarium, this internal aquarium filter is designed to improve water clarity and oxygenation. As a compact small tank filter it helps agitate the surface and supports a more stable environment for coldwater or tropical setups, making it a straightforward choice when you need better circulation without an external unit.

The unit includes biological filter media and the pipework needed for installation, and it assembles and disassembles quickly to make routine maintenance easier. A detachable spray bar can be used to create surface movement, act as a gentle wave maker or add extra aeration where required. It is also suited to odd-shaped or shallow habitats because it can be mounted horizontally or vertically and fully submerged, and the supplied suction cups help secure placement inside the tank.
