Ok so Im trying to dial in my two part dosing regimine and I have a question. I want my Alk and Calc in my frag system to be at 9dkh and 420ppm but when I mix up Reef Crystals to 1.025 the Alk and calc is 11dkh and 480ppm if not higher. How do you work around this? If I do a WC tonight wont it pike my levels up? then I'll have to wait for them to come down and then start daily dosing? I'm just having trouble understanding how to keep my system stable. My total water volume is 140 in the whole frag system. I usually do 15 gallon WC every two weeks. let me know what ya think.
