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 and paludariums 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.
