I have a custom sump for sale. I misjudged the room inside my stand and it's too big. Its 48x24x18. It has a 15 gallon ATO section, a 25 (ish) gallon fuge section, return section and big skimmer section. It is black and clear acrylic. It does have a descent size scratch on the outside lower right corner from putting into my stand. It has NOT ever been used but holds water just fine. It is for sump only. No socks or skimmer included.
