What would you recommend for the Fluval 404, used on a reef and fish tank...live rock, live sand, UV sterilizer, soft corals only?
What has been in there is two levels (the first four compartments from bottom up) of Chemi Pure carbon, then two levels of noodles in the top four compartments, with a sack of Purigen. And the first contact is the two sided sponges (actually four sponge units, two on each side).
