bit of a late entry here but my 90gal was on a piece of that pink foam since about 2004 when I got it (and prior to that the 90 that I had was also on foam, probably that same piece, for a year). I'm not sure what kind of trim it had on it, probably the same as they always use. I noticed when moving the tank (twice) that the foam was compressed around the edges like you noted, Shelley, and figured that that was just the way it is. I was also told to use the foam, not from the seastar peeps though.
I stripped the trim off my current tank, I don't know who made it but the bottom trim was almost flush with the bottom of the tank, there was no "offset" of the trim and glass. Regardless, the trim is gone and the tank is sitting on a large chunk of foam....I think. Hmm, in hindsight maybe I didn't use any foam. Man my mind is mush lately, you'd think I'd know that
