I live in Australia and am trying Rexolin APN which is recomended by many here..Just checking if this is the concentration of liquid trace that you are recomendingcazandchris;14735 said:thanks tom. when you say 15 mls per 75 ltr.As per your EI light suggestion for mixing 1Tbs of Dry trace mix to 250 mls then 20mls is equivalent to quarter of a tsp then my 150ltr tank needs 30mill/week?Am I correct? Would this be the same concentration as you are suggesting.
