dosing two part question
 

currently dosing two part, my need to maintain alk is way more demanding compared to my need to dose calcium. I believe this is because of my GFO and bio pellet reactors. So I have setup a dosing system for the alk and dose calcium manually as needed. My question is, Can I add the third part NACL free ballnig salts into my alk mixture and dose them together?

Cant answer your question about NACL, but using more alk then Ca is totally normal. I use way more alk then I do Ca, and i don't have pellets or gfo.
