I don’t know if there’s a study out there or not which could answer my question, but would you say that as alkalinity consumption of a reef tank slowly rises over time that the consumption of trace elements increases also? Or is trace element consumption independent of alkalinity consumption? Over the last month, the amount of ESV 2 part I’ve been dosing to my SPS dominant nano has increased from 16 ml to 21 ml and this has me wondering if trace elements are also being consumed at a greater rate.
