On New Years Day in 2017 I had a Red Sea Max S-650 fail on a seam at the bottom. Red Sea told me since the tank was 2 years old (tank Warranty was only for a year) that I would have to purchase a replacement tank for $1,052 plus shipping. I got my LFS involved who spoke to Red Sea on my behalf. Red Sea agreed to sell me one wholesale for $600. It was irritating that Red Sea would try to charge me retail for a tank that was only 2 years old when it failed. Looks like troubles with this tank has continued for Red Sea...
