Just so you know if your adding a balanced addative like Kalk for Every 2.8 dkh or 1.0meq/l you raise your alk you will raise your calcium by 20mg/l.

So if you want to raise your alk to 10dkh you will end up with a calcium level of aprox 490mg/l(don't want to get the calculator out to get an exact)

IMO this ratio would be a little unbalanced.

I would add some alk buffer ( I use baking soda myself) to bring your alk up alone to a higher level then use a balanced addative like kalk.

cheers
Hmmmm. So, should I be mixing 6-1 of Baking Soda/Washing soda. How do I introduce it to the tank? Drip? Dump it in? Then once I get the desired levels, I dose Kalk to maintain it?

I don't use the Baking soda/washing soda thing. Been there done that. Baked baking soda mixed with unbaked baking soda is supposed to work well but the baked baking soda doesn't like to dissolve in water.

So I just use baking soda.
Yes it drops your ph for a minute or so. Big deal. I see a drop of about 0.1 to 0.2 in my ph for 30 seconds.

Add is slowly and I just sprinkle it in the sump in a high flow area. I take about 30 seconds to add a teaspoon of baking soda to my tank. In my old system 90g tank and 75g sump If I remember correctly if I added about 8 teaspoons of baking soda it would raise my alk by 1.0meq/l.
