Hi, currently looking into KH director , so i been reading there are a lot of older models made, how can one distinguish between the older manufacturing and the newer ones? https://www.bulkreefsupply.com/kh-director-with-white-2-1-sa-4-pump-doser-ghl.html , is this one old or new model
I understand that it takes about 100 ML , which can add up in a small tank like mines (60g) and the 4 heads on the 2.1 doser are all used, by KH director and to dose alkalinity . Is it possible to add on a extra doser to dose fresh salt water for the make up of 100 mL salt water gone and dose Mag , CA , exactly which model is needed slave ? 2.1 maxi? or do you Need the Profliux to control more dosers
