Hy
Tank 360L or 96 Gallons
Light: 8 hours with 2 x PL 55W 7200k and a plenty of natural light (not direct light)
Substrate: Only river sand.
Fertilization: KCL 10 ppm every week after 50 % water change
NH3/NH4 and NO2: 0mg/L
NO3: 10mg/L
PO4: 10mg/L
The leaves of my Echinodorus Grandiflora is disappearing, some are turning brown others are come apart and i think that is the Fe missing.
I have bought EDTA and now i have some doubts:
1- The bottle of EDTA have 1 liter and i says two things, one is 0.01 mol/L and the other is M.=372.24 and i thing this tell me that i have in one liter 3.72 g or by others words 3.72g/L, is this correct?
2-So if i have 250 liters i should but directly from the bottle of EDTA 30 mL to have
0.1 ppm of Fe, is this correct?
3-I should put some compound with Iron ? EDTA only helps the plants to absorber the Fe, is this correct too?
Has you can see
Regards
