I was just testing my water parameters and grabbed my new Salifert Alk test kit by mistake as I still have a few tests in my old kit. Anyway I tested with the new one and my alk is 4.5dkh! I went and tested with my old one and got 8.0 dkh!

I mixed some new salt a couple days ago so I thought I would test it to see which test kit is out. Well I got 15.7 dkh! with the new test kit and the old test kit wouldn't even change on 1ml so I refilled it with reagent #2 and it took to .63ml to change the colour(1.63ml).

The salt is IO and is a couple of years old, I bought a whole bunch on sale.
My calcium is at 310 and tested at 380 last week.
PH is around 7.8 - 8.0
Phosphate is 0

So I am assuming that the old kit is not accurate and that my bucket of IO salt is bad as well.

Any comments would be appreciated.

I've always had consistent results between salifert kits. And I'd double check with a tird kit for bad salt, someone locally lost all their livestock recently due to alk off the scale with old IO salt.

Thanks Brad, I will try that and I am mixing up some new water with new salt.
