The Fluval U2 underwater/internal filter uses a total of five filter medias: 2 coarse foam, 2 poly/carbon pads, and 40 grams of ceramic bio-media. This is the one that you would need to replace frequently. The coarse foam can be rinsed out and re-used, being made of inert material. The ceramic bio-media can also be rinsed out, but should only be replaced if they are extremely dirty.
I do not know how ceramic bio-media can get dirty enough to the point that they will need to be thrown away, but I suppose it can happen. Here's a potential scenario, if you used copper to medicate the tank at some point in the past, and now you want to keep invertebrates, then yes, you will need to replace all of the media in your filter. Even the ones that are considered inert, since even a small trace of copper can harm your shrimp.
The Fluval U2 will run just fine without a poly/carbon pad installed. Set up as such, it will still function as a coarse mechanical filter and as a submerged biological filter. You just lose chemical filtration. This is an advantage to you during those times when you have to add medication to your tank.
How well does this filter pad do its job? It does a fine job of filtering out smaller particles. These are particles that are too small be captured by the coarse mechanical filter. However, it does a poor job of chemical filtration. This is not surprising, when you consider that this pad does not hold granular activated carbon. Instead, one side of the pad contains bonded carbon. There is very little actual carbon in the product. What you have is carbon bonded to the filter material.Read more ›
In the meantime, the Poly (Polyester) part of a Fluval U3 filtration system gets even smaller particles than the Foam.
SO while this works, I wouldn't recommend others do it if they can afford the FX series for water turtles. This is best for fish, and haven't had any problems with my feeder fish getting into this filter.
*Change out only one side(there are 2) at a time to keep the good biological bacteria.
