Any one ever had there tank blow out?

[sphelps]

There was a series of tanks in Saskatoon that came from a builder that had some defects. One large tank split at the seam, could have been improper cleaning of the polished edges prior to applying silicone. The others all had acrylic backs but the builder cut the acrylic to fit perfectly with no gap failing to realize acrylic has a higher thermal expansion than glass. The acrylic buckled eventually pushing the glass apart and split the seam.
