Ultra Clear Tanks by Ultum Nature Systems

Ultra Clear Rimless Aquarium mitered edge- Ultum Nature Systems | Aqua Lab Aquaria

These rimless aquariums are carefully crafted using 91% clarity Diamant glass, a highly transparent extra clear glass with very little residual green color.  The low iron content in the glass provides uninterrupted crystal clear visibility.  The 45° mitered edges are bonded together using high performance German silicone specifically designed for aquarium construction.  Rather than following the conventional sizing of other rimless aquarium brands, Ultum Nature Systems keeps the aquascaper in mind by focusing on the golden ratio.  The additional space makes it easier to achieve that sense of perspective and truly show depth in an aquascape.

Curated Equipment Starter Packs for Low Tech or High Tech Set-ups

We at Aqua Lab Aquaria have curated two sets of freshwater aquarium equipment that are perfectly suited to the 9 gallon 45U Ultra Clear Rimless Aquarium. With our Low Tech Equipment Bundle, you receive the necessities to start a healthy planted aquarium. We recommend sticking with easy plants for this set up. With our High Tech Equipment Bundle, you set yourself up for success by receiving all the equipment needed to create a lush and thriving planted aquarium. This bundle allows for greater plant density and variety. However, due to the more plentiful growth of plants and algae, your tank will require more maintenance and attention. Plus, using CO2 in your aquarium requires extra care to avoid the risk of depleting your fish of oxygen. This makes the High Tech Bundle better suited for aquarists with experience or those looking for a more committed aquatic experience. The Low Tech Bundle is perfect for beginners or those looking for low maintenance.
