Alk, CA and Hardness

[WarDaddy]

On 5/28 I had these numbers:

dKH 5.8
Alk 2.06
CA 430

I have gotten a CA reactor and Kalk reactor running about 4 weeks ago.

My numbers are now

dKH 10.6
Alk 3.44
CA 430

I have slowed the Kalk drip. are those numbers to high?

I've heard dKH between 5 and 12 is ok, as long as its stable and doesn't change.

Natural seawater is in the 8s.

I'm shooting for 8.

I think Ca in NSW is 300-320?

The target numbers are on the instructions for the Salifert kits. I think I remembered them correctly.

Cheers
Josh

War dkh is the same measument as meq/l for Alk.

Yes 2.06 meg/l is 5.8 dkh but 3.44 meg/l is 9.7 dkh.

Recomended alk range is from 7-11 dkh or 2.5 to 4.0 meq/l

I'd say you're looking pretty good.

Calcium should be around 420 ppm.
