I know everyone says it's easy but I've never set up a sump before and don't want to experiment on a 450 gallon. I have a large D.I.Y sterilite cart sump just need someone with expertise and know how to plumb it to the tank. Weekends are best I will buy all needed supplies and pay you for your time. Just pm me with your price and I will contact you. I'm located in the Wakefield section of the Bronx.
