The Bubble Magus BM-T12 is a sophisticated add-on dosing unit designed specifically to expand the capabilities of the existing BM-T11 system. This device seamlessly connects directly to the T11 base, providing additional precise channels for dispensing essential reef aquarium supplements such as calcium, alkalinity, trace elements, and food. It serves as an essential upgrade for hobbyists who require more dosing lines than the standard unit offers, ensuring accurate delivery of vital additives to maintain a stable marine environment.

Engineered with improved durability and precision, this add-on features a stylish new body form factor and tighter internal seam tolerances to better protect electronic components from moisture exposure. It utilizes high-quality German-made medical grade tubing to extend service life and includes an advanced alarm system that alerts users immediately if issues arise with the motor, tubing blockages, or circuit board errors. The unit supports a flow range of 1 to 1999 mL per cycle with an accuracy of plus or minus five percent, allowing for up to 24 automated dosing cycles daily via its digital DC control interface.

This specialized pump is the ideal solution for reef keepers looking to scale their chemical supplementation without replacing their entire dosing setup. It is best suited for aquarists managing complex reef systems that demand multiple independent nutrient inputs and require reliable, long-term performance. By integrating this unit with a BM-T11, hobbyists can achieve a highly customized and robust automated feeding regimen while benefiting from enhanced build quality and comprehensive safety monitoring features.
