My Alk is at 6.9/7.0 dkh. Calcium is 455 and ph 8.3. I want to get Alk to 8.5. I was told to use bicarbonate as it will not raise the PH. I can use the calulator to see what I need to get to 8.5 but my question is, how much water do I mix with how much bicarbonate? And then how much of that liquid do I dose per hour, day, week etc? Im told I can simply use baking soda? Thanks for any help.
