So I've been using a small aquamaxx calcium reactor on my reefer 250 for 6 months or more. And for some weird reason when I test my water sometimes my dkh is right in the range I want it, other times it's super low. But my mag and calcium are high. I have my reactor flow rate at 2.50 ml/per min. I've tested what comes out of the reactor, dkh from the reactor is at 55dkh.
Can anyone help me understand why this happens? And is there a way to prevent it?
