I have been doing some major research the past week and since my build is large I was debating between 3 part dosing and a calcium reactor.
The 3 part is a no brainer with a dosing pump. The calcium reactor is another whole story. I am presently looking at these two models.
Korallin C-3002 Calcium Reactor - AquaCave.com
And this model:
Saltwater Aquariums, Fish Tank Supplies, Aquarium Products and Reef Tank Equipment - GEO CR818 Calcium Reactor
Two questions;
1) Do I set the reactor up before or after the cycle?
and
2) Will I have to add some type of Magnesium media or still dose Magnesium overall?
FWIW:
I was using a GEO 618 before I had to tear down my previous system to move. I was very happy with the quality and ease of use of the GEO calcium reactor and will be using this same unit again when I am able to setup another large tank again. You won't need to setup the reactor until after the cycle because there will be no drain of calcium in the system. I would think with a system this large, you could wait a while longer before setting up one. I was using the course ARM media and did not have to dose additional Mag to my system in order to maintain calcium levels.
