Fluval U Underwater Filter BioMax, Replacement Aquarium Filter Media, A495

Fits my model and works well.

Used these for my Fluval water filter in my aquatic turtles tank. Exact replacement and works great. Shipping was timely.

Ive used several different filter systems on my various aquariums. I love this underwater one the most. No constant running water. It keeps the tank clean and the filter elements last a long time.

Works great.

always a good product

I bought this for my Fluval Edge and although it is basically loose in the box I managed to figure out a way that works for me and my tank. After rinsing it very well, before replacing the old biomax, I cut some white replacement filter foam that is way thinner than the original Fluval filter foams and fold it in there so its not loose in my grey plastic filter holder. I cant put too much because there is limited space in the holder for everything the tank needs but I get enough in there that works out well. I would recommend and buy it again.

We have a couple turtles and this has helped a lot. I keeps the water cleaner for longer, and keeps it from looking yellow.

Works

Great aquarium filter

Dont need it
