I'm currently in the planning phase of a shrimp-only high tech nano. I'm either going to be using a Fluval G3 or an Eheim Ecco Pro 200. Is there any filter media that is strongly advised? And similarly, is there any to avoid? I'm still undecided about what to stick in it, but currently its either Snowballs or (if my budget allows) King Kongs or Pandas. Any other pointers you guys have on top would also be greatly received!
