|laqu||and i can just use a cut up yoga mat?|

Yeah, I think the words get a little confusing and are interchanged for each other. Typically, you want the mat to prevent stress points/compensate for irregularities on the surface.
You also want a level surface, but the mat won't do much for that. using a piece of plywood with shims is probably the best/easiest solution for a countertop or some other fixed object that you can't directly level/shim.

I am going to say you probably want more than edge support ( like an acrylic tank). solid top would be fine.
I was under the impression that it is a good preventative measure, catastrophic failure or cost of a mat? Yeah, I am going with a mat.

When people say they put a mat under the tank to account for the base not being perfectly level, do they really mean flat? The two are different and I just wanted to be sure. I’m planning to set up a tank on a countertop that should be level but may not be exactly. I was going to use a mat to account for irregularities but if being level is the true issue, I would also have to use a sheet of something like plywood that I could shim as necessary.
Also, does a rimless tank need full support on the bottom or can it just be edge supported like on a rimmed tank? I was going make a small stand for a 12 gallon long and was wondering if it needed a “top”.

|talontsiawd||I put a mat under my tank, rimless or not (I have only had one rimless tank). I just think is a good idea, especially with a rimless tank. As much as starting over is a pain, it will be less painful than having to deal with a leak later on.|

Shock absorption has some value, but the leveling effect IMHO is much more important. When I do a 50% W/C I hear the load being taken off the stand by the creaking of the plywood top my 40 gl sits on. Being an Acrylic it will be more forgiving flex then the joints on a glass tank will be.

|prototyp3||I think Hollywood has tricked many of us when it comes to earthquakes.. If you aren't at the center, you basically get a bunch of rocking. A tank in decent condition can take some uneven pressure like that for short durations no problem. Now the issue is when a tank isn't level and is subjected to continued stress over the course of months and years. That's when you get failures.|

|Scyry||Has anyone tried a cork sheet? It is pretty much water proof, a little spongy and thin.|

I'd say that the main purpose of the mat is the prevention/reduction of continuous everyday static stresses on tank structure from surface imperfections, not protection against earthquakes.

Easy there sparky, I'm just the messenger. According to what I was told the building shook, swayed, moved when it should have been stationary. Secondly, I was also told that Mr. Amano uses some sort of cork board but it's not exactly cork it is made of a wood found in Japan that absorbed the shock preventing the tanks from cracking, similar to the mats but firmer and thicker.
Now do the mats relieve stress from the tank, of course it does. It also serves as a buffer if you will between the vibrating equipment like filters and such from transferring to the tank. It's like a sound dampening mat. It absorbs sound, vibrations from getting to the tank and relieves pressure points as well.
Have you ever worked with Dynomat or other sound dampening systems before? If you have same principle.

|jkan0228||Fantastic explanation. Thanks so much. Looks like foam is very good stuff.|

Oh wasnt meaning to come on strong, sorry if it seemed that way. That's the problem with non verbal communication, too much is lost. It prevents the glass from cracking because it evenly distributes the downward pressure of the aquarium and it's contents onto the stand, instead of having pressure points. Imagine those matress commercials that show pressure points on the back, it's quite a bit like that. Now when you have localized pressure points plus harmonic motion like an earthquake or even a person walking by without a care (fairly unlikely), the glass can break. That little bit of foam distributes the shock of harmonic energy throughout the bottom of the tank, instead of to specific pressure points creaded by surface imperfections in both the aquarium glass and the stand top.
I mentioned the walking thing because it's the same principle, though walking is much larger scale because there are quite a number of shock absorbtion systems built into our body, incluting the arch of your foot, bent knees, discs in your back, your glutes, calf muscles, to name a few. But the brain and optic nerve are quite a lot more sensitive than some aquarium glass This came to mind because i remember a guy who had several vertebra in his back fused and started having problems with headaches, and noticed pronounced vibration in his vision when he stepped. That would suck!
