Fluval U3 Underwater Filter Poly/Carbon

Pricey for what they are but they get the job done.

As expected

Is what it Is...

Great product easy to clean last long

Definitely a need if you own a Fluval U3 Filter.

Everyone knows that carbon filtered water, such as water that has been put through a Brita filter, knows it is far higher quality in taste. I can assure that with the advantage of a carbon filter your pets will thank you in their own way for removing potentially harmful chemicals from your tank. In the meantime, the Poly (Polyester) part of a Fluval U3 filtration system gets even smaller particles than the Foam.

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.

This is what i expected and is a great price compared to the pet store. will be buying this again in the future

Good
