    Rated 5 out of 5 by from Good product I bought this about 2 weeks ago now and this filter is absolutely amazing! I would never buy top fin filters again they are a waste of money ! I wish I would of bought this from the begging! My water is so clear and it has take no care of my algae problem too:) the one I bought in store came with a pump so I no longer needed to use my loud air stone! This fluval is so quiet! I also use the fluval water heater and it is also amazing!! Buy fluval NOT top fin!

    Rated 5 out of 5 by from Awesome pump My Whisper pump kept malfunctioning so I purchases this Fluval U3. It is quiet and very powerful. Really moves water through the pump. Did tank maintenance (planting, cleaning) and then installed new pump and within a few hours the water was crystal clear and the fish seem very lively and thriving. Caught this jewel on sale but I will only buy Fluval in the future sale or not.

    Rated 5 out of 5 by from Great for planted tanks I purchased this about 3 months ago for my 45 gallon bow front planted tank, it's done an amazing job keeping the water crystal clear.

    Rated 5 out of 5 by from I have been using this filter for 9 years already. I have had to replace it a couple times cuz it wore out but it keeps my water moving and really clear. The Pet Smart store in town used to carry it but doesn't anymore so I hope it doesn't become unavailable online as well as I will still need to buy the replacement filters and carbon modules.

    Rated 5 out of 5 by from all in one filter Can't beat the price $29.99 It is internal so no worries about leaks or overflow. 3 output options. The top output with venturi provides lots of surface movement = more oxygen exchange. 3 filters, mechanical = foam filter, chemical = carbon filter, and biological = bio max filter.

    Asked by: sueknowsalot
    Yes this is for a 40 gallon tank, the current would be way too strong for a betta.

    I want to hook up a small tube to the output to pump to a waterfall display. Is this possible with this model?

    Asked by: Munstroven
    If the acccessories on the 'outlet' tube can be removed, then I think this should pump another 12" maybe 24" above the water line
