Reviews
Simply awesome!
"I researched reef tank offerings extensively before pulling the trigger on the R90. Zero disappointments with the whole setup! Aesthetically perfect. The doors are easily pulled from their magnetic fasteners. Cord management system is a nice touch as is the small drawer. Delivery was fast and well protected on its shipping pallet."
Beautiful in looks & engineering
"I am all praise and have not one criticism concerning the UNS R150. It’s just excellent in every way. For me, the best features are the already assembled cabinet with a great sump and magnetic doors. I also love how beautifully all of my electronics fit comfortably in the area set aside for it. It hides everything perfectly. My only suggestion would be to have a large paper getting started Guide."
Best purchase for 2025
"Customer service team did an excellent job regarding the delivery of my R60 Tank. While waiting for my delivery, the customer service team stayed in constant contact with myself via email with updates on the delivery with regard to estimated time of arrival. I’m extremely satisfied with Glass Aqua and will continue to use this company as my go to supplier for all aquatic needs."
Fantastic customer support
"An amazing system from an amazing vendor! Glass Aqua was very responsive in the face of unfavorable shipping and delivery conditions and willing to work with me through every step of remediation, making sure I was satisfied with the resolution! The tank is absolutely beautiful 😍"
