those are boosters for your kh and your gh.
you MAY need to add them, if your kh and gh are too low without them. if you do need to add them, it would be cheaper to use a dry gh booster (ive had one jar of seachem equilibrium for years), and use baking soda for kh boosting (carbonates are carbonates, go for the cheap package).
