Hey guys.. I'm looking at building a marine tank, this is all new to me and I'd really appreciate any help or advice I can get! The tank size I'm looking at building is 1600x600x576. I currently have a tropical tank of 1200x500x500, which I've been advised to convert into the sump & sub divided into a fresh water section as well. What's your take on this? Also in terms of equipment what size skimmer ex would you recommend? Thanks!
