I currently have 5 tanks setup, 110, 2-100 gallon long tanks, 1-75 gallon, and 1-40 gallon tall. As for tanks not setup let me see if I can count... 2-125 gallon tanks, 4-75 gallon tanks, 2-40 gallon breeder tanks, 6-20 gallon tanks, 1-55 gallon, 1-265 gallon, 1-30 gallon breeder, 1-40 gallon hex, 1-30 gallon hex. hmmm so I have over 400 gallons running now and almost 1200 gallons un setup! I have a major issue. Sick thing Is I plan to setup all these tanks. My stock has been greatly decreased by disease but I'm ready to attack the hobby full force soon as I have a door to my basement so I can move the tanks down there. OH GOD! I'm planning a 300 gallon stock tank filter to handle all the tanks at once! I'm INSANE!!!! And I still want to setup 2 600-1000 gallon display tanks and 1 300 gallon planted display tank!
