The bacteria definitely doesn't matter - bacteria adapt easily from salt to fresh to salt.

The tank will be 12' long x 3 ' deep and 28" tall plus sump. Im guessing the total water volume would come in close to a 1000 gals. So the wc will be prob 100 to 200 gals monthly. Im not sure what kind of tank it is yet as its a new build.
