Amoeba said:I was thinking whether it would make sense to soak the substrate in PMDD. If I understand the theory correctly this way it would pick up some Fe, Mn, Zn, Cu and Co.
Iv'e been "charging" a batch of akadama for three days, so far only with Ca + Mg + K.
Along the lines of Amoeba's question, would the akadama take in any micros?
I was thinking of adding Trace and FeSO4 for a couple of days.
