Hello, I'm just getting the last bits of information to jump into salt water and was at the LFS
today looking at all the different options. I know a lot of people go with a sump but I'm curious about a canister filter (along with a skimmer on both)? Is there an advantage of one over the other? I was heading down the sump path (as per the questions about holes in the tank with my previous post) but wondering if a canister, like a fluval or ehiem, might do the trick as well. I know that people have even used hang off the back power filters but just wondering about the different options. As for my setup I think it's going to be a 120gal with live rock, fish and hope to add corals down the road. Thanks so much...
