Will this measure alk too? Or will you need to buy the standard director as well

also, does this have an auto water change function?

It will not test alk. The reasons why are explained in this thread.

The Ion will not do water changes as it is a water tester. The Prodilix 4 can do water changes with the Maxi doser
