Ok this sounds like fun
Things you can run in a fluval:
1. Carbon
2. Ammonia absorb, chips, whatever
3. The bio matrix blocks that come with it.
4. Poly filter
5. Phosguard or other phosphate sponge.
6. Crushed coral if doing a substrate change
7. filter floss ( but not your old gym socks)
8. Live rock, hey why not.
9. Nitrate sponge.
10. Bio balls ( I suppose but why?)
Now my list of what not to run in a fluval is somewhat longer and I won't boar you with it.
