Great article @Randy Holmes-Farley top notch stuff as always. I currently dos kalk through a kalk stirrer but my tank is starting to take up more alk than i can dos with kalk in a day. I knwo your not suppose to use soda ash when using kalk. Wonder what is okay to use to boost up alk back to comfortable level besides a CaRX. Would sodium bicarbonate be okay if dosed into different section of sump to supplement alk supply? Sorry if i missed a recipe for this you have posted somewhere.
Thanks for all you do.
