Based on just looking at the photos of your tank, i'd wager the consumption isn't crazy across the board and the red sea traces are could potentially be unnecessary, and as
@Perry mentioned above, waterchanges with a well balanced salt could replenish, or you could switch to a well balanced 3/4part alk/ca/mg with balanced traces.
As corals grow or new corals are added, the tank will become more densely populated as a result, and consumption will exponentially increase to where waterchanges or 3/4part won't keep up in a balanced way. At this point, RS Colors or another trace method should be considered
