I have a Red Sea 170 the cracked on the bottom pane. It was crazy one day it was running perfect next it was dripping on both right and left corners. Probably got 5 gallons of salt water on my floor before I noticed it. I jumped into action and transferred the coral and livestock to my 220 gallon and drained the tank as fast as I could. Scraped up all my live sand and put it into a rubber maid with some water. Long story short I contacted Red Sea and they sent me a new tank. Although they asked for a lot of pictures. Luckily I took detailed video and pictures of the incident.
