Should look into the IM nuvo fusions. They stopped doing their old curved corner tanks as they were having issues with them developing leaks. I have both the nuvo 10 and nuvo 20. I love them both, but if I were to do it again I would have gone with 2 of the 20 gallons. But they 10 gallon is still pretty nice. After sand and rock it's only about 7-8 gallons of actual water tho. But the 20 is way more worth it in the end having the chamber for the skimmer and another chamber for reactor/heater/fuge/etc.
