Help with my salt alk and ca issue

Hey guys,

 

For the longest time, my salinity would rise from 1.025 to 1.028 a week after the water change... That's with an ato!

 

I discovered that my doser was causing it to rise. I turned off the doser and the salt stabilized.

 

My calcium and magnesium aren't dropping much but alkalinity is...

 

How should I go about dosing correctly to avoid the issue again?

 

The doser runs:

Alk 12 pm, 6pm, etc

CA 3:05, 9:05pm, etc

Mg 2am, 2pm

How much alk are you using? My tank consumes about 30 ml per day and I spread my dosing schedule out at 3 hour intervals.

 

From what little I have read, apparently dosing 2 part will raise salinity.

 

Here are a couple of threads from the RC chemistry forum:
