12 Volt Man;3958188; said:the ones we get here in Ontario are fine for two tanks. they are designed to hold two.
I used to have a 90/65 stacked among others for years and years.
the thing to remember is that although tube steel is light, it is incredibly strong.
my old fishroom with all metal tube stands:
also, my new fishroom (150g) with a tube stand made with 1.5" tube steel.
the point is, they are extremely strong.
I agree that they are strong enough to hold two tanks, but designed for two??? I don't think so. You need at least enough room to open the lid and have it fold all the way back, with two 75gal you couldn't do that. But just OK for a 65 on the bottom like you had.
I had one of these stands for my 50gal years back. It was made of 1" tube. Boy did that sucker sway back and forth with any sideways force on it!! Would have welcomed 1.5" tube for sure.
