SO
I took in some water to get tested today. They use Salifert just like me.
Salinity 1.026
Alk 8.1 dKH
Ca 380
Mg 1230
Much better numbers than I got. I purchased a new Salifert Ca kit (they didn't have Mg unfortunately) and just tested with the new kit and got 380 as well.
I guess both tests were bad in the perfect way. To both give low readings while maintaining the expected Ca/Mg ratio. I thought it might be user error so I had the guy at the LFS show me how he tested. It was no different than how I was using the kits and how I retested when I got home today.
The numbers are still a little low so I decided to transition to Reef Crystals anyway. To transition should I just start doing water changes with the new salt? 10% of water volume at a time?
