2.3 grams according to that site.

18.4 grams will produce 8dkh for 76 litres.

If this site is correct.

No probs. That measure only covers the alkalinity used it won't cover the acid produced.

Today's update (did the tests a while ago, just forgot to post)

Everything was the same EXCEPT the kH dropped to between 6 and 7. No drop in ammonia or pH, which is peculiar.
Also, tested for nitrites just in case, none yet.

Yeh this is a bit strange. I could understand kh dropping without a ph drop as the kh could still be absorbing the acidity but early on in the cycle ph dropped significantly whilst kh remained at 8dkh

I was confused by that too, yesterday I even ran the kH test twice. I didn't understand why pH would plummet and kH remain the same. But now the pH seems to be holding and kH dropping instead? That is more what we would have expected all along, yes?

That's exactly what I would have expected. Crazy stuff.

I'm surprised by the lack of nitrites. If NH3/N4 has dropped from 16 to 12 I would have thought there would be nitrites. Have you considered that nitrites might be so high that the kit is unable to read it and your getting a false zero reading?
