Hi, I have a sump running on a 110 gallon but i have very small particles running in the water and thought about getting a UV Sterilizer or Diatom Filter. I am trying to save a few bucks by throwing another pump into the sump running at 1300gph(already own) and attaching a 50 micron filter sock at the output which will run back into the sump. Will this work? Or should i just get the Diatom or Sterilizer?
