Good luck, all mine did was frustrate me.
I had one that was 31" deep and all I can say is take care when building your stand. I'm only 6 foot and the stand was too tall for me to reach anything. I had an eight foot ladder to do cleanings and still couldn't reach the back of the tank.
Unless the tank can be accessed from the back, you must have one heck of a reach. If I did the math right, it's about 50 inches from the front top to the back bottom. I drop to much stuff, have to many frags fall, for me to ever do the washing machine build again.
