I would almost bet that your tank was not curved when it was installed. It has sagged over time, and would likely respond well with having a solid and much wider series of supports under it.
Ya, at one time your tank and those angle iron supports under your tank were straight across and not curved. They don't make curve angle iron. They were obviously not strong enough. (The way there attached doesn't look good at all to me either.) I think you have found why other people reported a problem. Good thing you checked. Best to fix it now.
