Can Kalk be used to fully supplement Ca and Alk?

[wojo]

after 2 days after i unplugged the kalk reactor my ph dropped to 8.2 today. today i bought up the Ca to 420 and Alk to 3.5 meq/l, the ph is at 8.4 right now. i dont have any kalkwasser mix handy at the moment so i cant do the test you mentioned Randy.

what should i do now, should i plug in the Kalk reactor and watch the values daily?

i would like to get away from dosing 2part every day and only use Kalk to supplement both but i dont know if its possible.

if it comes to that, why would i ever need Kalk reactor then?

thanks
