Fluval U3 Underwater Filter Poly/Carbon

It works as its supposed to be

Best way to buy these supplies!

monthly aquarium maintenance

I used this filter in my small turtle pool for about 2 years. Then it just stopped working all together. It was regularly cleaned and never treated roughly. I would never waste my money purchasing this type filter again. I even replaced the filters as needed. What a waste of money. I now use a different companys filter system and all works fine.

i highly reccomend this product. Easy to install and very easy to change out. I only use this filter media for my under water filter.

Used in a turtle tank. I should get a stronger filter as these are expensive and must be changed frequently.

Keeping the tank clean good product

Great product easy to clean last long

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.

It seems to be working well with the rest of the system.
