Hey just got a 100gal tank off craigslist, pretty happy with it so far today. Noticed these bubble like stuff along the seals of the glass when I filled it up to check for leaks, is this normal or do I need to have it rebuilt?uploadfromtaptalk1407010297555.jpg

*EDIT: its only on one sides, between front panel and right side panel.
