Imho.
place your tank on the floor.
The structure of your stand is very important and that goes down to the person's knowledge and integrity of not cutting corners during the process....
its alot easier to do maintenance on the floor too.
I know its not that shiok to put it on the floor but for me, its a trade off for getting a bigger tank.
I had the same concern for about a year and eventually settled for a floor tank (Fgt with glass panel).
and frankly speaking, nothing last forever, it will come to a point whereby you'll need to change a new tank after few years, having a floor tank makes it alot easier to do the logistics (for my case).
Big project needs more planning but its very satisfying upon completion.
