KH Director + SA + Slave doser

[CEVetU]

Hi everyone! I have a Stand Alone 2.1 doser, I was thinking of buying a KH Director with a 2.1 Slave pump, will this setup work without a profilux? Will I still be able to use both pumps and the KH Director, all being “directed” by the Stand Alone doser? If yes, which doser should be used to feed the KH Director? The SA or the Slave?

Also, what supplement do you guys normally use to adjust ALK using the KH Director in automatic mode?
