Calcium Supplementation

[zachluhrs]

Does anyone use both a Calcium Reactor and the kalkwasser drip method on their reef?

I use a calcium reactor and a kalk reactor on my tank. My kalkwasser is used for my top off water via a dosing pump that is connected to a float switch.

Yes, plenty of people use both. Usually it is because limewater alone does not meet their calcium and alkalinity demand, and the CaCO3/CO2 reactor alone leads to too low of pH.
