That said, there are quite a number of ways to maintain these parameters, and the best methods do not generally involve buying independent additives for each.

This has pros and cons of the various methods:

For ca & mg I like BRS they are easy to mix and the reef calculator makes dosing easy

Besides DIY stuff I've found BRS to be the cheapest.
