I bought this used 90 gallon Hagen tank 6 years ago and got it up and running. I had a tiger oscar, named Phil, he just passed away. He was almost 8 years old. So when he passed, I decided to take the tank down and take all the glass panels apart and do a fresh seal on all the seams. Needless to say, I did this right in time avoiding disaster. The top trim basically just pulled right off with ease. I started scraping off the old silicone, and curiously pulled the side and front panel to test for integrity. It literally just pulled apart with very little force. Like I was putting my socks on kind of force. The seams started bubbling about 4 years ago, so I really pushed my luck with this tank. Please, if your seams look this bad, take it apart and do a full rebuild of the tank. Just a warning to people who may not know better.
