The UNS Stem Plant Holding System 90 - Triple Decker is a sleek, high-capacity setup designed for easy organization, effortless maintenance, and optimal plant growth. Whether you're a serious hobbyist, a collector, or looking to streamline your plant care, this system can hold up to 279 potted aquarium plants. The compact design allows you to efficiently stock, grow, and showcase hundreds of aquatic plants in a neatly organized setup.

Featuring 3 stacked shallow all-in-one tanks, this system allows for easy access and unrestricted plant growth, all housed in a durable aluminum stand that saves space without compromising stability. Each tank has its own filtration system and adjustable flow control, so you can tailor water circulation to your plants' needs. The included potted plant trays let you arrange plants in customizable tiers, ensuring taller stems get the support they need while keeping everything neat and accessible.

Maintenance is a breeze thanks to the centralized plumbing system, allowing you to perform water changes across all three tanks at once. With adjustable water flow, you can direct circulation to the surface or beneath the trays, keeping plants healthy while flushing out debris with minimal effort. Plus, the system supports inline CO2 injection, ensuring optimal plant growth while keeping your setup clean and organized.

Whether you're managing an aquascaping project, cultivating a personal aquatic plant nursery, or simply looking for a functional display, the UNS Triple Decker Holding System delivers a professional, high-capacity solution. Its versatile design seamlessly integrates into any setup.
