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

Thank you

This product is much cheaper here than it is at my local pet store this product does everything it says

Maintains my crystal clear 55 gallon tank.

I have a Fluval U2 filter for a 10-gallon aquarium in which I keep a Red Ear Slider turtle. I change these out once every 3-4 weeks. It works surprisingly well, Red Ear Slider turtles are dirty. One box of these has enough in it to fill my filter twice.

I got this to fill the cartridge of my U4 filter. They seem to be working as expected and I am happy with them.

More of the same when it comes to the Fluval system parts.

Works great with the Fluval filter and helps keep the water the cleanest. The filter keeps things cleaner longer with this product.

I got the new filter when my old one broke an was skeptical that this would work as well with more pads and biomax. Works well

always a good product
