Fluval U2 Underwater Aquarium Filter 110 Litre (30 US Gal)

Product Information

Having the option of being able to direct the flow left to right and/or up and down gives greater flexibilty and is a function easily achieved by the manufacturer at little cost. The whole filter hinges forward for complete removal from the aquarium, leaving the fixing bracket in situ.

i cannot see no ripples or hear anything, its just silent, although if i put my hand near the middle of the filter i can definitely feel something coming out.Top output for increased circulation and oxygenation, spray bar for a gentle flow designed for planted aquariums and the bottom output designed for deep water circulation.

The premium grade absorbent carbon removes odours and discoloration from the aquarium creating crystal clear, clean water and healthy fish. But what baffles me is should I have it on the one that aerates the water or the on the gentle mid flow or should I have it on gentle flow and aerate at regular intervals?Aqualease Ltd t/a Complete Aquatics is authorised and regulated by the Financial Conduct Authority, register number 729918 and act as a credit broker and not a lender.
