The Interpet internal cartridge filter CF1 will process the water inside your aquarium to keep it clean and healthy for your fish.

Ideal for use in both coldwater or tropical aquariums, this filter boasts an effective five-stage filtration system that will create healthy water for your fish to thrive.

The water is drawn in through the powerful yet silent pump before it passes through biomedia, mechanical floss, carbon and an Algaway pad before being pumped back into the aquarium whilst the clear filter cover will stop fish from ever entering the filter.

What's more each element of the filtration process is easily replaced when their effectiveness begins to diminish!
