Neptunian Cube Replacement Filter Sock

What is the Neptunian Filter Bag?

The Neptunian Filter Bag is a 4" filter sock that can be used in your Neptunian Cube Aquarium to remove any undissolved particles from your water. Filter socks easily remove waste including leftover food, organic debris and fish waste, reducing the required effort it takes to manually remove such small particles yourself.

Filter socks are an excellent way to easily keep your aquarium water as clear as possible, whilst not adding any added stress to your filtration system.

The Neptunian Filter Bag provides fine mechanical filtration that polishes your water, and is easy to install in your system.

Which aquariums can the Neptunian Filter Bag be used with?

The Neptunian Filter Bag is a standard sized 4" filter sock that can fit in all Neptunian Cube aquariums, except for the Neptunian Cube T40 and Neptunian Cube T45 Nano tanks. It is important to check compatibility before purchasing for use with other aquariums.
