Interpet Internal Aquarium Fish Tank Mini Power Filter, Cleans Water, for Coldwater & Tropical Aquariums Up to 40 Litre

FILTRATION FOR A CLEANER, HEALTHIER AQUARIUM – four stage filtration, removes particulate waste, toxic chemicals, and odours from the aquarium
SIMPLE FLOW CONTROL AND DIRECTIONAL CONTROL – the flow rate can be adjusted to full or more gentle flow if you have delicate fish, use the flow deflector to direct the water to the surface or to the side of the aquarium
BENEFICIAL BACTERIA – once established, the good bacteria will thrive on the plain foams within the filter and break down the waste (excess fish food, plant matter, fish waste) to keep water clean and healthy for your fish
EASY TO INSTALL – the PF filter comes with an easy-to-use fixing bracket. The bracket and suckers can be left in place while the filter is removed from the aquarium for cleaning
AERATES THE AQUARIUM WATER – the powerful venturi thoroughly aerates the water, by increasing circulation of the aquarium water and thus the surface area (this can be turned to off position if you prefer)
