I had a 300g FO which was 30" Tall and cleaning it was tough.
My reef tank is 96x33x29. Entirely open top, and I have to hire someone with long arms to keep the bottom 3" of the tank coraline free.
No question the taller you go the better looking the tank will be. But the practical side of maintaining it is a different story.
My recommendation is start with a tape measure and go from your arm pit to your thumb, and make sure the tank is less than that if you are going to maintain it entirely on your own.
