Return pump advice needed

[birkhoferfan15]

I was leaning towards a Dart for my return pump, but I really don't want to drill the tank I'm making my sump out of. Does anyone know of a good submersible pump that would move a lot of water on my 125? Thanks in advance

How many gal is your overflow rated for? I would say either a Mag Drive or Quiet One.
