I've had my 110 for a little over 10 years now. Never seen any problem with it. Moved it over 6 times (what a pain in the a**). Recently drilled, praying to God it doesn't give out.

Now, on the otherhand, my Father has a 75 reef ready from Oceanic. One of the side panels was sliding slowly out of position. At that time, Oceanic had a 5yr warranty on the tank from defects. This was at about 8~9 years of ownership. He called, and they replaced the tank, and sent someone to Houston to do the transfer from bad tank to new. That's a deal!
