I would like to get my alk in the 8.5 range but I am having problems getting it about 8 and maintaining it there. My calcium is around 390 which I would like to get up to 420 or so. My ph is at 8.42. I am using soda ash at this point but I am wondering if I should switch to plain baking soda? Is there a specific way that I should be doing this to get to the levels that I want and to maintain them? It feels as though dosing one just pushes down the other and vise versa.
Thanks
