Innovative Marine - MiniMax Sump - All-In-One Media Reactor The MiniMax Sump All-In-One Media Reactor is a novel approach to optimize chemical and biological filtration for aquariums utilizing a sump for filtration. Its innovative Patent Pending design minimizes the need for flexible tubes, pvc pipes, ball valves, thumb screws, and unnecessary clutter that are usually associated with typical media reactors. Its ingenious design maximizes performance and offers out of the box responsive flow control, easy maintenance, low power consumption, and the smallest of footprints. The versatile MiniMax SUMP reactor is designed with an acrylic pedestal and discreetly hides the included pump. The clever adjustable flow indicator dial allows for precise tuning and easy reference points to min to max flow rates. The MiniMax is the All-In-One Sump Reactor for minimizing time and maximizing filtration. Responsive Flow Control - Unique dual chamber design, allows for quick and responsive flow control within seconds with a simple turn of knob without the need for ball valves and inlet/outlet pipes. New min/max settings allow for precise tuning with flow indicator measurements Silencing Sleeve - Slide sleeve up/down to eliminate water noise caused by low water levels Efficiency - Utilizes upward flow pattern that requires less flow and lower energy consumption Eliminate Messy Maintenance - Internal chamber acts as a removable cartridge that simply slides out of outer chamber and automatically drains water out without the need for tools and time consuming thumb screws to unfasten. Made for Sumps - Space saving design with a small footprint (4.33" diameter 9.64" high)
