- Fluval U4 Media Review by Brian-D
I have a Fluval U4 Underwater Filter and have been looking for replacement Media and BioMax pellets over the net for weeks now, because the 1 local store has finally closed down that carried them.
Fluval is a great pump for fish or aquarium, quiet and very effective in keeping it clean.
ValuePets was very easy to order from and very quick to process and recieve the order, I would highly recomment their services. (Posted on 2/24/13)
