chelat cu 12% - 0,09g
molibdenit (the source of mn) - 0,09ml
h3bo3 - 1g
kno3 - one spoon
mgso4 - one spoon
k2so4 - two spoons

My parametrs
no3 - 0
ph - 7
kh - 10
gh - 16
co2 - 40
fe - 0,3

In my aquarium grow vary well plants and long green alge.I have hard water
and to reach 0,3 ppm of fe i must dosage 15 ml of my own fertilizer like up.

alive and grow.
