Chris Ozment's 435 Gallon Reef Display

By Leonard Ho - Posted Dec 22, 2011 09:00 AM
Large tanks are inherently cool. Chris Ozment's 435 gallon (1650 liter) reef takes the cool factor and runs away with it! Started in January, 2010, this large "low profile" aquarium has filled out very nicely. Many large fish now patrol over healthy and supremely colorful coral colonies.

Chris' impressive 435 gallon reef display is filled with vibrant and well-balanced colors.

Chris' aquarium is featured as Atlanta Reef Club's (ARC) Tank of the Quarter, where you can see many more photos.  Well deserved!  We plan to follow the progress of this aquarium and hopefully share it as an Advanced Aquarist Feature Aquarium in the future.  For now, enjoy the tank overview and the many splendid photos.

I'm a passionate aquarist of over 30 years, a coral reef lover, and the blog editor for Advanced Aquarist. While aquarium gadgets interest me, it's really livestock (especially fish), artistry of aquariums, and "method behind the madness" processes that captivate my attention.
