Fluval U3 Underwater Filter Poly/Carbon

Works as expect for crystal clear water.

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.

Is what it Is...

monthly aquarium maintenance

These allways work.

Should have checked the reviews first before buying these. First off they are a cheap version of what I needed, second they arrived dirty and stained with something I can only describe as looks like boogers on them. Very disappointed.

Best way to buy these supplies!

They fit perfectly into my turtles filter and keep water clean for at least 1 1/2 week my turtle is pretty big so its a good product to buy

Turtles are messy critters, especially if you feed them a varied diet with some plants. Differently, give a turtle a live feeder fish, and its gone in seconds without a trace. However, turtles need plants in order to be healthy, despite the mess. Roughly, half of the plant they will eat, and the other half they will rip to shreds! This makes it such that turtles need a foam filter to catch the larger particles, which in this case are stirred up by the Fluval U3 water jet for easier collection via the Fluval U3 holster. Without Filter Foam Pads and a Fluval Underwater Filter, it is difficult to be vigilant to get waste particles siphoned. It is such that in my experience more waste particles will settle bottom of a tank without Fluval Underwater filtration. What is great about these pads is that they can be washed and reused many many times. They dont need replacing every time, just cleaning. I rinse them until they come clean when I siphon/clean the tank.
