Picked up a few 150g Rubbermaid Stock tanks today=) one is for a QT on my parents koi pond and the other is mine for this prohect when it gets rolling my dad's buddy also gave me a free 55g acrylic tank..Not sure what it will end up being used for yet it anything but the 150rubbermaid will either end up being a sump, refugium, or a nice big water change chamber,..
