    Too Powerful!!!

    By JDBR on Jan 21, 2022

    I bought this for my 10gal Betts tank, the flow is WAY too powerful even on its lowest setting. Would not recommend using this for a Betts tank.

    Good little filter.

    By melle on Jun 11, 2021

    I love the filter. It puts much needed oxygen back to my water of the tank. I have installed on my 20long shrimp tank. This tank is very heavily stocked with shrimp and fish. I also run a back up filter in the tank. The fluval is my main filter. It worked so well at clearing out the tank. The one thing I am not a fan of is the size of the filter and how much space it takes up. Plus this is NOT shrimp safe. First time I went to clean the impeller. There where so many young shrimp in my filter. I have added extra floss so they can not get into now. As far as ppl saying it's to power full. You can adjust the flow, and there are ways to baffle the flow as well. It is a great filter. I do recommend I love the filter. It puts much needed oxygen back to my water of the tank.

Some of the reviews, seem ppl did not reach out, mistakes happen. Life goes on. It's not a reason to slam a good product. … more

    Piece of crap

    By Toadman69 on Mar 10, 2021

    Fitting on the filter for the spray bar was broken out of the box so I was unable to attach the spray bar. Pretty powerful, a bit too powerful if your tank is shallow or you have frogs or turtles

    Did not come complete.

    By Filter on Feb 22, 2021

    It came already open. It was missing the spray bar, a pieces of foam, and two other small pieces as well. Looks like a returned item that they borrowed parts from.

    By Chelle on Feb 21, 2021

    I just bought a second, love this filter but you have to make sure it's fully sealed! Fully submersible.

    Very quiet filter

    By Brie on Nov 7, 2020

    I have my tank next to my bed and its very quiet. I have to listen for it to hear it. I use this for a 20 gallon tank with bettas and endlers and it seems to be keeping the tank pretty clean without creating too much movement

    Loud and inefficient

    By fish12 on Aug 3, 2020

    The filter was loud and kept me from being able to sleep. My betta fish was also disturbed by it. The flow was strong. It didn’t filter the tank the way my Whisper IQ 10 did. I would recommend that filter for betta fish. As long as you turn the flow down to less than half. It catches more debris and the outflow is gentle.

    Terrific product, well-built, easy to install & maintain, great price.

    By GILMAN on Apr 28, 2020

    Although it's only rated for up to a 15 gallon tank, we have it installed in a 29 gallon. After a 5 minute set-up and installation it took only 12 hours to clear the tank's water from cloudy to crystal clear. (Granted we have NO fish in it, hahaha), But we love the (adjustable) overflowing trickle sound it produces and this does it perfectly. We've used the older, larger external Fluval filters and they're great, but this one's all we need. I only wish Fluval made a similar one for up to 30-40 gallon tanks but I suppose I could purchase another one since they're very inexpensive.
