Reactors & Dosing

Dosing pumps and reactors

As corals grow, they use up calcium and alkalinity. Our dosing pumps and reactors help you replace them automatically. That makes your water much more stable than dosing by hand.

Which one do you need?

A dosing pump adds small amounts of liquid additives throughout the day. A calcium reactor dissolves media to supply calcium and alkalinity, so it suits tanks full of stony corals. Media reactors, on the other hand, tumble carbon or GFO for better filter media performance.

Common questions

When should I get a dosing pump?

Once you find yourself dosing alkalinity by hand every day, a doser saves time and keeps levels steadier.
