When I built my acrylic tank, I had planned on doing discus but halfway through the build my wife convinced me to go saltwater. The dimensions of the current tank aren't as friendly to a saltwater setup so I'm planning on a new build. Acrylic gets crazy expensive once you go past 10' so I'm going to go the plywood route this time. I'm thinking of doing a large flat back hex, around 300 gallons. I've never had a flat back hex and nobody local has one, any thoughts on that style of tank or that type of build? Obviously the angles present the biggest challenge.
