Rimless Tanks

Ultum Nature Systems ultra-clear rimless aquariums feature 45 degree mitered edges. The low iron glass used features 91% clarity promising you an unbridled aquascape viewing experience. UNS tanks also feature deeper dimensions that follow the golden rule more closely than competing brands. UNS aquariums also come with a black nano-foam leveling mat, ensuring your aquarium has proper cushioning on your desk, table, or where ever you decide to hold your underwater masterpiece.
