Cal/Mag/Alk....Dosing pump or reactor?

[Reef.ductionist]

A calcium reactor and dosing pump can both be connected to a controller and in case of power failure could be programmed to trip an alarm or send an email alert. I would prefer a doser only because increasing or decreasing the calcium would be a breeze...and changing calcium sources would be easier if I wanted to switch to the ‘ Balling Method’ of calcium dosing for example. Could even increase or decrease calcium while on vacation or travelling, there is no need to
physically remove calcium reactor media etcetc...on the other hand having a calcium reactor hanging around the tank also looks neat too.
