This confirmed my guest earlier. You are running lower NO3 level. It is not only because Fe dosing. Even though you have plenty bioload, and over feed them, the N is still low, that N form is not easily absorbed by the plants (have to be decomposed first, takes time) as easy as N, we dose from dry KNO3, instant N.


Looks like you dose low. If everything is fine, I will not change a thing. Just wonders why.


Yes, I have been using this too. Recently bought a 500ml Nutrafin Plant Gro Iron Enriched with the new label. I must say the contents is the same as previous. Only different I think of, beside new label, is the dosing instruction. 10 ml per 75.6 liter now, 10 ml per 70 liter previously.
It is a good micros fert, IME, have been using it on my 2.5 feet tank, right from the start. The only thing is to figure out right amount to dose for your specific tank. The dosing instruction says 10ml/75.6liter, so roughly you will need 30ml for your 60g tank weekly (0.3 mg/l Fe). If you to dose daily (better, I think), you will need 10ml to provide 0.1 mg/l Fe daily. So economically, it is a lot cheaper. Hope this will help you to decide further.

Bought Nutrafin Plant Gro Iron Enriched (RM 22.50) and Plant Gro NPK (RM22.00) from 88Marine.
