LIFEREEF SVS24 in-sump skimmer with gate valve and Mag-Drive 9.5 B pump. Suitable for up to 250g. Works great. Recent citric acid bath. Any pump at 900gpm or higer can be used. 22.5" tall - here's a link https://www.lifereef.com/venturi.html to Life Reef's site with more details. Pick-up in Hopkinton, MA. I also have a LIFEREEF model B sump for free if you take the skimmer (the second image is the actual sump - the third is from Life Reef's website).
