Hey guys, I am using this salt and thought I would post my test results. This is after 24 hours of mixing and measured with Salifert test kits:
Ca: 370
Alk: 8.0
To be fair, it was only mixed to 34psu (measured with a 35psu solution calibrated refractometer). I bought this salt to use with the zeovit method, and was looking for around 7.0 alk and 420 calcium, so I will be looking elsewhere when this bucket runs out.
edit: also wanted to note both of my kits expire in 2013, but I am getting near the end of the reagent used to titrate in both kits. Should that affect results?
