I wouldn't worry about dosing anything for some time yet. You won't know anything until your tank is set up and has been running for awhile. Then it is time to buy some good quality test kits and see if you really need to dose anything at all. Never dose anything without testing for it first. Some salts have a fairly high calcium content to it to begin with and it may be awhile before your system starts using up more than you are adding with your water changes.
