top level manufacturer of tanks, although the only 2 tanks i have ever had leak on me were both oceanic bowfronts. one a 175 gal and one a 92 gal, their warranty administration SUCKS!!!. took me a full year for them to make good on the 175 leaker, luckily i had room for the fish in other tanks. But as a rule they make great aquariums I guess i just had bad luck on those 2 occasions but the way they process the warranty is pitiful
