Frequently Asked Questions
What is the difference between the ReefDose 4 and ReefDose 2?
The ReefDose 4 has four dosing heads while the ReefDose 2 has two. Both use the same precision gear-motor technology. Choose the 4-head model if you dose more than two additives or plan to expand your dosing program.
Do I need the tubing kit separately?
Yes. The ReefDose pump does not include dosing tubing. You will need a Red Sea Deluxe 4-Color Tubing & Accessories Kit (sold separately) to connect your additives.
Can I add more heads later?
The ReefDose 4 comes with all four heads included. If you only need two heads now, consider starting with the ReefDose 2 and adding heads later, as the system is designed for modular expansion.
