Thinking of an 'easy' upgrade - advice on tank and stand wanted

[The Grizz]

You can tell if it's a good tank from kijiji just by looking at it in person. I recently got a RSM 250 off kijiji and it's a beauty.

First thing I do is look at the silicone. Color, feel & thickness. If its clear, not hard as a rock or peeling its good.

Second is the glass for the obvious, scratches. Is the thickness correct for size of tank ( only if it's not from a manufacture ) & last thing is it tempered. Plus if it's a manufacted tank that has the trim, what is the condition and is it still solidly attached.
