My alk is 6 and cal is 460. I’m gonna start dosing 2 part( sodium carb and cal). I need to correct the alk first right by adding sodium carb or bicarbonate.? Then once I have my alk at 8.5. I will leave my tank alone for one week and I will test how low my alk and cal went down to and that will determine my daily dosing? Is this process correct? Should I also stop putting Kalk in my ato?
