I have a Reef Keeper Plus that includes an ATO option and hardware. But, I need a tested plan for the rest of the project. My sump is low at floor level and I would like at least 5 gallons and hopefully 10 gallons. The tank is in tight quarters in a corner with enough room to store the container. I'm thinking of using a tall plastic wrapping paper container and I'm trying to figure out how not to have the water syphoned out. Any suggestions with pictures?
