What's going on here?
Was futzing around with my tank just now and noticed some what appear to be cracks? Upon closer inspection, I don't think they are cracks, but maybe it's where the adhesive/caulk that holds the top rim to the glass may have separated from the glass?
Honestly, I have no idea, and I don't how serious this is, or even if it's serious at all. Any info or advice y'all might have would be awesome.
(Thought about posting this in the Equipment sub-forum, if it needs to go there I'll delete and re-post)
