Okay so I've decided to go with a Calcium Reactor as oppose to dosing pumps. I've done some research and I know both have their pros and cons but I want to give the reactor a chance and see what happens. Since Im not really familiar with these and the different brands I wanted to see if you guys could help me choose one. There are 3 different ones that Im looking at so I will list them below along with price and everything included with each.\n\nGEO 618 Reactor w/Ehiem 1048 Pump\nReef Fanatic Co2 Deluxe Regulator\nReef Fanatic pH Controller\nReef Fanatic 10lb Co2 Tank\nThe only thing I would need to replace is a few hoses, a maxi jet 1200 feed pump and new ph probe.
