Opinions needed: mag-drive pump size for a 120 gallon?

  1. AquaticIshy Initiate Member

    Hello,

    I'd like to get opinions on what some people use for their larger tanks (100+ gallons).


    I'm building another sump for a new 120 gallon tank. It's a non-drilled tank. I was considering getting a dual overflow box (with 2 draining systems instead of one, with one (possibly two) return pumps. What would he monster tank keepers on here recommend? The tank will be housing a few fingerling butterfly koi until they are big enough to be released into the pond in my complex.

    Any input would be greatly appreciated.
