I just wanted to give everyone here an update on the stand....
It looks like I am dealing with some top-notch companies here.
Drs Foster & smith got the stand to me in less than 3 days, and offered me compensation right away when they heard it had some minor damage. I told them to wait until I heard from United Pet Group (Marineland) about my safety concern.
United Pet Group had me send them some photos of my concern. They responded they would test a new stand there and then send it to me. It'll take a few weeks, but I'd rather wait and do it right. I like that they will test it there first so I will be assured I won't get another stand with the same problem. Wow!
(By the way, I did a reality check with my wife and she had the same concern)
