I can't seem to find the answer to this question. Hopefully someone can help me? I have two 1.5 inch ID bulheads, one in each seperate overflow on my 300 gal. Using Stockmans or Dorso standpipes I'd like to run one overflow through my sump with skimmer at about 1000 gal per hour and hook a closed loop up directly to the other Overflow with four returns in the tank. Anyone see why this wouldn't work or do I have to pump it out of the sump? Thanks
