Converting A Saltwater Tank To Freshwater

    Moved into a new house and have to get another tank (cross brace on the 46 bow broke).

    I have a deal on a 72 gal bowfront drilled with overflow, a sump tank and a protein skimmer.

    Stupid question number one: does the pump on the octopus protein skimmer just push water thru the skimmer or does it also pump water back up to the display tank?

    Stupid question number 2: what do I need to put into the sump in the way of dividers or baffles to make it function as a freshwater sump?

    Thanks in advance for insight and advice!

    I can answer question two:

    Bubbles float in saltwater and freshwater. A normal bubble wall design would work well, probably better than in saltwater as the salt makes things more buoyant.

    My assumption was that bubble traps were not as important in a freshwater set up, for the same reason that the protein skimmer won't really be helpful (bubbles form but not nearly as well).

    I have to admit, I was shocked to find there were no baffles whatsoever in the sump when I went to look at the tank.
