From what I've learned you have to raise Alk very VERY slowly. Do it through Water Changes weekly. The alternative is to drip small amounts daily and slowly bring Alk up throughout a week or so.

Did you test your new Saltwater before WC's?

I am using the Salifert titration kit. There is a test mixture of dKH 6.1 which I am able to test exactly too so I trust my method is good. I do weekly 10% water changes with Instant Ocean. I am due for a water change in a few days so I will test the fresh mix then.

I found this page and with baking soda I raised my dKH from 5.1 to 5.7 I have a batch of salt water mixing overnight and I will measure the dKH of that tomorrow.

This morning dKH in the tank was still 5.7 and the fresh mix of IO was dKH 9.3 which I think is accurate. I did a 10% water change and then dKH in the tank measured 6.7

This is a raise of more than 1 dKH point in 18 hours which is probably on the outside of the comfortable curve but fish and coral look fine.
