Hello everyone Ive been in the hobby for about 2 years now and have been contemplating a custom tank build. I have 2 150 gallon tanks now one a 150 tall and a 150 half moon. I have some larger tangs that are starting to out grow the 150 half moon . So I was thinking about doing a 450 gallon L shaped corner tank with a drop off. Any comments things I should be aware off I've built a few tanks but nothin of this size. I have a few drawing.
