Hello ... I have a 300 freshwater tank that is getting to small. I want to build a 1500 - 2000 gallon tank to replace it but I dont know where to start. My tank is a room divider where you can view from 3 sides. I was thinking about a 5 ft tall 4 ft wide 9ft long. I have a number of large dirty fish so my filtration needs to be able to handle it. I live on a slab so I thought about using a steel frame with large view areas. Any ideas
