Sound proof a tank cabinet?

Check out some of the material used in the auto sound industry. Dynomat is a popular one that people use to keep sound in. Expensive though. I built a small box to go around my return pump from my basement sump to my 1st floor display. I lined the inside of this box with dynomat to keep the noise down. Pretty effective.

Dynomat is not going ot be much help. It is an asphalt based product used to dampen low frequency panel vibrations, not absorb a broad spectrum of sound.
Melamine foam based sound products would be a much better choice based on their absorbtion characteristics.

Carpet padding is fairly transparent to sound. The melamine foam and other engineered products work oponentially better (at a cost of course). If the carpet padding helped, then the sound absorbing products would have made it dead silent 
If it is dead silent, then the noise was not bad to begin with.

melamine based foam can come in many forms and densities. Most carpet foams and mattress foams are polyurethane foams

Bingo. I do this for a living.
When we want to help isolate higher frequencies, we use a CLOSED CELL foam. Regardless of what it's made out of, I believe that's the key. Please take into account that whatever you put in there may get wet at one point or another. So items like carpet padding may not be the best choice for mold/mildew prevention. Try something like Ensolite or Overkill:

EDIT: And I had a friend who made a cheap/quick/poor attempt at a sound room in his house using carpet padding. Definitely helped a lot. But hanging anything soft over all those solid flat walls would help. You could staple a group of 3rd graders to the wall for improvement.

Buy the 4 sheet pack. Should be plenty. If you have extra, it will only help to double it up around the noisy components.
Is there cheaper versions of it? I don't know. I work in mobile electronics, so that's what I use. lol But if you find anything, let us know!

Well that product is made nice and compact because you probably deal with small spaces so you need a product to meet those needs.
I am wondering if something really simple like Styrofoam would do a good job if it were really thick? I have tons of space so it makes more sense to use something that is cheap and less efficient but just use more of it.

Styrofoam is just ok.... you need products engineered to absorb a broad range of higher frequencies. Owens Corning 703 and 705 panels are well regarded and not too expensive... they will beat the sox off of styrofoam.
