Low pH & Carbonate Hardness

Also, your specific gravity is low. 1.024 is suitable for fish tanks, but reef tanks should be 1.026 which helps keep all elements at reef values. However, since your calcium is already so high from the RB salt, I would be hesitant to increase SG right now.

I would question testing kit/method. My RBS never mixed that high. Usually around 430ppm
