As a general rule you should never dose your tank for items you do not test for. By adding an additive to your tank and not testing you wont know if your adding to much, if your not adding enough or even if its needed.
Every tank is uniqe. One tank might require 2X as much calcium as another tank simply because of the amount of rock/corals.
Most tanks that are simply FOWLR
dont need calicum to be added as long as regular and frequent water changes are done.
