bought this for a turtle tank. I have a 55 gallon tank that is about 1/3 full with my 2 full grown red-eared slider turtles. filter appears to work in that it runs, media gets dirty, water does come out. I have even removed and replaced at least half the water in the tank. However my tank water continues to get worse and worst.
Bought this for my turtles tank. Very disappointed. After the first few weeks it stopped filtering properly. We had to clean the tank every week just to keep up with the demand that the filter wasn't. Now it's been just over 2 months and it stopped working all together. Save your money anf find better a different filter.
I bought the Fluval U4 when I made the recent transition of my goldfish from a 39 to a 55 gallon tank. Since this tank would be located near the bedroom, *quiet* was one of the top criteria of the new filter. The Fluval filter has indeed delivered on its promise to be quiet. It is marginally audible at all, fully submerged in the water. This is in stark contrast to the previous filter I used, a hang-on-back style filter that created so much ambient noise it was a constant distraction. There is an optional valve that can be installed on top of the U4 that pulls in air to push bubbles out with the water. However, this requires the top to be above the water line, and I found this to be a bit too noisy for my liking. Instead, I have an air stone bubbler set up in front of one of the jets of this filter, such that it pushes forward a column of bubbles that the fish love. It's easy to disassemble and clean, and relatively unobtrusive in a 55 gallon tank. So far, I'm very happy with my purchase
This filter is awesome. No more listening to water run. It keeps water clear and is absolutely silent.
I ordered alot of thing for my sons new turtle. I would love to use the filter but it did not cone with suction cups
This thing just simply does not do a very good job at all. Water has never been so dirty.
i’ve had this turtle tank for less than 3 months and it doesn’t keep my tank clean the water is murky within 3 days after cleaning it out.
I have really mixed feelings on this. I’ve had it for 4 months and it’s worked amazing! Super easily to clean, adjust water flow, and I love the sleek look. Today I unplugged it to clean it then plugged it back in and it won’t run. Regardless of what I do. Like the other reviews said, really frustrating. I haven’t decided if I’ll buy another because I really like the filter.
Haven had this long but of the three internal filters I bought, this one is the quietest and easy to use.
My cats love the chunky Turkey, so I figured we’d give this a try. They won’t touch it. Too bad. They are so picky. I’ve tried so many FF flavors, and even the flavors they used to eat they will not touch.
