Thank you very much for your input
We're trying to get our DKH as close as possible to NSW which is 7 all of
our lab tests in every batch shows 7-9. The reason that we write 9 is that
it will be probably the highest value you'll get and if it drops then 7 is
its lowest value. ( what kind of test do you use?) In fact it is easy for us
to raise the DKH but we avoid it since several tests with higher DKH in our
salt showed a certain of un balanced ions relations with ca and mg. What
important to us and to you is that ionic balance much more if it's 7 or 8.
However 6 is on the lowest value and a care must be taken to avoid a sharp
drop of DKH. If corals react good to the water change in means that you have
nothing to worry about and the DKH is fine.

Please note that the NA2HCO3 in the mixture is a minor element and in 15
liters of water it can vary between 6-9.( I'm pretty sure that the full
bucket will give you these results. Also you may have a bad batch with lower
DKH. Please update me about the reaction of corals, what is the batch and
lot number on your bucket. We'll make this test on that lot sample that we
have in our lab and let you know the results.

Thank you for using Royal Nature product line
Looking forward to having your answer soon
If you have a phone contact number I'll be glad to chat with you on phone
about it.

Subject: infos for kh value in salt

Hello,
I am writing for a technical question about your salt. I repeated three
times this test, having same results:

15 liters of pure water mixed with salt, to have salinity 35%, at 25
degree of temperature, running in a tank with pump for 24 hours. Tested
the Kh value thereafter with Tropic Marine test and resulting always in
a value of about 6. I think that is a low value for this salt, compared
to your declaration of 9dkh.
I used a 10-kilos new salt, and each time I shaked it before mixing salt
in the water. Other persons I know found the same problem, too.

Note that the same test with a different salt leads to kh=9dkh ...


Hope you can give some insight
Many thanks
Filippo

ho fatto la prova portando la densità a 1.028, e così facendo ha quasi raggiunto kh =7.

Allego i valori che sono misurati in Mar Rosso (da cui dovrebbe provenire il sale RN)

Fosfati : non misurabili.
Nitriti, nitrati : non misurabili
Calcio 480
Magnesio 1600
Ph : 8,2
Kh : 7
Densità : 1028 / 1032 salinità 40 °/°°
