Hi all!

After mixing a fresh batch of this salt I get a low ph..

PH = 7? or below... I can't tell cause my test kit doesn't even show a color, it is clear...

It also mixed to 7.5dkh and 420ppm calcium, so I added 3ml of B-Ionic.
Which brought it to 10dkh and 440ppm calcium...

I tested it again today after letting it set. The dkh is now back down to 9??

What am I doing wrong? Is it ok to use this low ph water change water?

I think I would question the test kit. I mix this salt and get:

Ph 8.1
Alk 11.8
Calcium 500
