Did you get that from the LFS or from AGA....
That's the same "arguement" I used when I wanted their stand.."It's 24"x72" should "'fit"...
But they were concerned with the extra weight of the 210 tank and water...
If the LFS is selling you a 180 stand for your 210...I'd reinforce it...
If they're sellling you a "new/redesigned" 210 stand...I'd stilll reinforce it...
But that's just me...
