Then i moved out and left it with my ex sooooo i want to get another tank going. i have my eye on a 45 gallon acrylic tank someone is selling it and the NICE stand for 100 bucks including some base rock, heater, filter with extra bio bag, temp guage, net, and test kit for $100 i cant pass it up the tank has no scratches or anything she said.
