We have consistently had some low trace elements in our mixed reef system from several ICP analyses. Thinking about using Red Sea Bioactive D, but can’t seem to find what their special blend of 18 herbs and spices are. Does anyone actually know? Is this published anywhere? We use other red sea additives so would be easy to incorporate. Manganese, molybdenum, strontium, zinc, lithium always low (Manganese always zero). We do their dosing for their iron additive based on Calcium consumption which according to the bottle should also add back manganese and zinc. Tank is a 170 gallon mixed reef some SPS, and a goodly mix of LPS and softies. Ca 400, mag 1400, alk 9 we use Red Sea coral pro salt. Thanks for the input
