When you start to think that you are doing the things right in this hobby, there's always a new thing that tells you that you're wrong. That's my case with KH and CA dosing. I have been dosing BRS two-part to my reef tank for about 5-6 months. Was a little hard to find the point and maintain my levels. I'm actually dosing daily 18ml of KH solution, and 9ml of CA solution to maintain 445 CA, 8 dKH... But someone just told me that I need to be dosing equal parts of KH, CA to my reef. This means that if I am dosing 18ml of KH, I need to be dosing 18ml of CA.. but I just don't understand why. With my current dosing, everything maintains its levels but I need to know if I am wrong! Any help????? Thank you
