Canister filter suggestions for a 29g.

The xp3 idea came from rex grigg. He said he had a xp2 on his 29g and wished it was a xp3. How much more flow is there? If I drill out the spray bar a bit that would help wouldn't it?

On a different note. What should i run in there as far as filter media goes? I don't really want much chemical filteration do I?

Hey thanks for all the responses. I'm very appreciative.
