DOS - Dosing And Fluid Metering System

A multi-purpose dosing and fluid delivery system of uncompromising quality combined with the simplicity of Apex Fusion software wizards for operations such as:

  • 2 part dosing
  • Liquid food dosing
  • Additive delivery
  • Micro-quantity dosing
  • Auto water changes


An elegant and highly refined solution to two-part/liquid storage, the DOS Dual Reservoir's advanced features are Apex Ready!

Automated water changes

Water changes with the DOS are super easy. All you do is place your empty vessel and your fresh stock of saltwater under your stand. Then, with the Apex Fusion wizard just tell it an amount of water you want to change over what length of time and the hours of the day you want it to happen and it figures it all out for you. It will perform an automatic, continuous water change for you. It gets better. If you have our dual optical water sensing accessory Apex Fusion will send you an email or text message letting you know it is time to change out the jugs. Less time pumping, siphoning, and sloshing water and more time enjoying a great aquarium.
