Do I need to switch salt?

I dosed calcium for the first time yesterday with the advantage calcium powder and its back up to 400ppm so I will continue to test to see how fast it's depleted. My alkalinity is up abit too now (about 6.8-7dkh) since using the reef builder. Everyone is doing fine, so I will continue to check daily until I get a trend of some sort.
