VCA Flow Kit for UNS Reef System

Upgrade your Ultum Nature Systems Reef System with this optional but highly recommended VCA Outflow Adapter and Random Flow Generator for improved water movement and circulation. Designed to fit seamlessly onto the return plumbing of your UNS Reef System, the adapter provides a subtle downward angle to position the Loc-Line® return nozzle deeper into the tank for better flow direction.

The VCA Random Flow Generator uses a patented internal design to create natural, randomized water movement—no moving parts, electricity, or added heat required. This enhances overall flow, keeps debris suspended for better filtration, and increases circulation without disturbing delicate corals or substrate. It’s quiet, efficient, and super easy to install.
