Calcium , Mag, and Alk questions

[fernalfer]

Ok i started dosing Kalkwasser in my ATO but when doing my test my Calcium was crazy high and my Alk was always around 7 dKh and Magnesium was 1290. Because the Calcium was so high and know it can start to precipitate if the other levels don't jive.

So i stopped the Kalkwasser. I have continued my weekly water changes but my last few readings were as follows

Calcium=490
Magnesium=1290
Alk=6dKh (low)
PH=8.1

So my question is how do i just get Alkalinity up and Magnesium up?

And once they are at proper levels can i start dosing Kalkwasser again and maybe just supplement Magnesium as needed?

Just dose Alk from a 2 part setup. You can buy those seperately from the Ca part.

Same with Mg.

Any recommended brands to go with for dosing these supplements individually

BRS comes to mind or you can look up DIY recipes.

Baking soda for alk. Go slow. Once alk and Ca are in range you will be able to dose limewater, as they are consumed at a similar ratio.

Baking soda for Alk? How would i dose that? Is there some type of dosing calculator for this?

There are a number of free ones on the web. BRS is a RC sponsor, so here is the link to theirs
