Works well
I have a hard time finding these where I live. Easy to replace in my filter and works well

Great quality unless you build your own filters.
Go with the name brand. Save the headache.

Works great
fit like they should, some people don't like this filter in the reviews but they do a decent job and are easy to take to take out and rinse.

Special water filters for aquariums
Can’t find these in stores any more. Happy I could find them on Amazon. They fit my aquarium filter perfectly

Works
I use the U4 along with Fluval's hangon tank filter in a 55g for water turtles. They together keep the tank ok and cheaper right now than the FX I want. But this is short term solution and they filters are at opposite ends of tank to push together dirty water. SO while this works, I wouldn't recommend others do it if they can afford the FX series for water turtles. This is best for fish, and haven't had any problems with my feeder fish getting into this filter. *Change out only one side(there are 2) at a time to keep the good biological bacteria.

Quality filter
I have had this filter on subscription for 2+ years and will continue to use them until my turtles water filter quits working.

Great
These were pretty durable. They dont stay clean long tho if you have turtles.

Not for my fish
I'm using this product for myself in the shower. I found it will remove the epidermis cells with ease. Cleaning up the product is a jif. I believe based on these facts for me, probably then, it would also make a good product for cleansing the tank.

Fits and works. I used to clean them. Now I let these go two months and replace. Little maintenance.
