Kalk and two part

[CristianD]

I don't know if this has been discussed, but when do u dose both ( kalk thru top off) and two part (dosing pumps) or just dose two part.
I just started dosing two part (bubble magus doser) and I'm concerned that my ph will go up to high with dosing and kalk also. Any input if I should do both or just dose two part?

If you can maintain the pH, Alk and Ca++ with kalk alone, as it has it all for Ca++ Alk and pH. Also, all of it is used up without leaving a bunch of Sodium or Chloride behind like two-parts
