Frequently Asked Questions

What is the difference between the ReefDose 2 and ReefDose 4?
The ReefDose 2 has two dosing heads while the ReefDose 4 has four. Both use the same precision gear-motor technology. The 2-head model is ideal for two-part dosing or a simpler supplement routine.

Can I add more heads later?
Yes. The ReefDose system is modular — you can purchase additional dosing heads separately to expand from 2 to 4 heads as your dosing program grows.

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.
