ahh ok, I remembered correctly.
I would just keep doing water changes on schedule with the new salt and see if that raises your alk
What salt did you switch from and go to? Also, when you dose for alkalinity it can affect the ph too,actually quite significantly depending on the product, just a thought.
And one more question! lol What test kit are you using for alk
? For alk
,calcium,phosphates and magnesium I would suggest going with salifert or elos, really accurate and very easy to use.
