Today has been one of the worst days of reefing in my ten years of experience. My red sea-250 system busted at the bottom seam spilling about 30 gallon of water onto my carpeted floor. I spent the whole day trying to save fish and my house. red sea is known to have issues with their seams. No surprise there since they are so thin and flimsy. Tank was in service for only a couple years, granted I bought it used but the seams appeared to be fine when I bought it. Even so, a tank lasting 2 years that costs as much as a red sea system is highway robbery. Just needed to vent. Buyer beware!
