Marineland has a new series of deep tanks all 36" deep and 36x36 150gal, up to 72x36 or 90x36 300 gal. Has anyone seen one? I spoke to the perfecto rep( manufacturer) who said the tanks outsold their estimates and are very popular. The shops around DC and Baltimore know nothing about them and the only way to see one is to order one and buy it. Given their depth it might be the best option now.
