Dosing
The maker doses this by schedule rather than by a fixed potency, so the calculator cannot use it. Follow the directions below.
How it’s used
Dose daily 1:1 with Iron+ (Trace-Colors C), i.e., 1 ml per 100 L per 20 ppm of Ca consumed. No leading element can be tested; dosing follows calcium uptake.
Cautions
• Overdose can severely damage coral soft tissue and stress crustaceans; coral darkening is a common sign
• Overdose remedy: change 50% of the water and halve the dose

Sources
Blend of 18 trace elements; Red Sea publishes no per-ml concentration for any of them, so no effects. Dose is ratio-based (1:1 with Iron+ / by Ca uptake).
