Neptune Systems DOS + DDR Combo

The most complete dosing system for your reef or advanced aquarium - configured to plug directly into any APEX system! Imagine an aquarium world of automatic water changes, micro-quantity dosing options, or set-it-and-forget-it delivery of liquid foods and supplements. The DOS is powered by dual peristaltic pumps. These pumps are designed to push precise doses of calcium, liquid fish food, water, or any other liquid substance directly to your tank. Unlike other dosing systems on the market, the DOS features industrial-grade stepper motors on its pumps. Unlike a brushed motor, these motors last longer and provide improved accuracy when dosing & the option for variable speeds. Compression fittings on the tubing attachments also help prevent air in the line for optimal performance. Replacing the DOS pumps requires no annoying lubrication or small parts - simply install a new pump head and snap it on for 6 to 7 hundred more hours of pump life. The highlight of the DOS system though is the APEX Fusion software control. Simple software allows you to input the amount of mL over time, and the dashboard figures it out for you. THAT simple. The dashboard then easily allows you to monitor DOS performance metrics and action.

But what about the DOS Dual Reservoir? The ultimate companion for your DOS - makes your dosing as 'set it and forget it' as possible. Each side stores two Liters of your required dosing fluid. Strong, cast-acrylic construction means a lifetime of durability. A low-profile design means less chance of knock overs when you're working around your tank. Connect directly to your DOS - and, with your APEX monitoring system - the included Optical sensor will even alert you when levels are low and need replenished.
