I don't dose regularly at the moment, after a rough year and a half of a new job my tank was pretty rough -- I'm just doing hefty weekly water changes with Tropic Marin. When I did dose, I usually did B-ionic for Cal/Alk because I was too busy to manage a full kalk regimen, and too poor for a Calcium Reactor... The key is testing for anything you dose on -- there is no magic formula, every tank is different -- the usage of various trace elements is entirely dependent on what you have the tank stocked with..

I wouldn't use tap water for a dip, instead use RO/DI with the buffers.. The tap, while probably ok, is definitely going to have more potential problematic elements than RO/DI -- the buffers will supply any that are essential.
