It's nice to get back here. I've been out of the hobby for a few years after my 70 gallon reef crashed, but I'm looking to get back,albeit at a smaller level. I'm thiinking of setting up a 70 gallon fish only tank, and I was wondering about some things. Would there be an advantage to a sump with a DSB for filtration for this type of system? I was thinking I would get a 30 gallon tank to use as a sump/refugium, and keep some algae in it for additional filtration. Any thoughts on this setup? Would it be appropriate for fish only?
