I have been away from the hobby for 20 years and after looking at all the new technology I've decided to give reefing another try. I have an Oceanic 48 gal flat back hex. Back in the day I used wet/dry systems and an Eheim canister filter. This time I am going to incorporate a sump w/ a protein skimmer and refugium. I am thinking of converting the eheim to a carbon reactor. Any advice or help is more than welcome. :fish:
