Which is better?

Which of the following options would provide the best filtration and/or best benefit to a 14g nano?

1. Keep the bio balls.
2. Replace the bio balls with a mini-fuge filled with caulerpa or chaetomorpha or both.
3. Replace the bio balls with a protein skimmer.

Currently my bio load is two small false percs, a peppermint shrimp, a brittle star, snails, hermit crabs, and four assorted frags.

probably either option 2, or 3 would work great.  Most people tend to stay away from bioballs, because they are "nitrate factories".

Just two small false percula clowns, for now.

Thanks everybody.  So I will go with the mini-fuge.  My BioCube has three filtration chambers.  The first chamber holds 2 mangroves and the Oceanic filter pad w/ carbon. 

The second chamber will hold the mini-fuge, which can have up to 4 compartments.  I am thinking to put filter floss in the first, cheato in the second, chemi-pure in the third, and purigen in the fourth.

The third chamber holds a sponge, the return pump and 4 more mangroves.

Any input on this configuration would be greatly appreciated.  Also, will I need to provide lighting for the cheato?  I could also put some cheato (or other decorative macroalgae) in the main tank.

Go with option two and check out the filter media baskets at http://shop.mediabaskets.com/.
