What size tank. How often do you change water. How much. As what's listed doesn't sound like a high demand for calcium that wouldn't be replenished with water changes weekly.
Water changes every 2 weeks 20%.
Planing on adding more lps and later down the road sps.
Started aquavitro line and red sea A&B for a few weeks and all was well for a while and then I lost 2 fishes in an overnite ph drop.
