Designed from the bottom up specifically for reef aquariums, Red Sea’s ReefDose comes with 2 or 4 bespoke (patent-pending) dosing heads that are so precise, they keep a consistent daily dosing schedule to the accuracy of a single drop. ReefDose offers a variety of smart dosing options for each head that are automatically combined into a coordinated daily dosing schedule for the complete device. The ReefDose features include: 4 Automatic dosing programs - Single dose, Hourly dose, Custom dose, Timer schedule Automated scheduling – combines all your dosing heads programs into one coordinated schedule. Missed dose compensation - compensates scheduled doses that you may have missed due to unplanned events. Supplement volume monitor – notifies you in advance when it’s time for a re-fill. 3 Dosing flow rates – including a “whisper” mode for quieter operation. Dosing queue & dosing log – See your heads’ upcoming scheduled doses, and review a detailed record of your dosing activity. Food head – set any head as a “Food Head” to trigger “Feed mode” in the ReefBeat App (which can be programmed to turn off all pumps prior to dosing).
