The M-Rack dosing tube holder is manufactured from industry standard Perspex cell cast acrylic. This guarantees a part of the highest quality that will last for many years underwater without affecting water quality and will not break down over time.

This rack still looks black under the blue LED lighting!

Clears up to 5x 5mm dosing tubes and is sold as a pack of 2. Use two side lock M-Rack PUKs to create a handy loop outside the tank or crankcase if required!

This rack requires one M-Rack magnet PUK per shelf - sold separately.
