Possible fertilizer? (chelated Fe w/ minerals)
I originally posted this on rec.aquaria, and was referred
here. (Sorry for those to whom its a repeat.)
I'm looking for a good substitute for the expensive
fertilizers such as Ferrovit and Tetra brands. I've found a
product that is chelated Fe plus other minerals and contains
no N as nitrates, ites, or ammoniums and no phosphates.
Its label reads as follows:
Mg 0.50% (chelated) Mn 0.25% (chelated)
Sulfur 3.90% (combined) Zn 0.50% (chelated)
Boron 0.02% Cu 0.25% (chelated)
Fe 6.00% (chelated)
Secondary and trace minerals derived from sulfonates of
these, and the chelating agent is lignin sulfonate.
Could i use this product safely? I have considered
ordering Dupla from Pet Warehouse, but it seems there
should be a cheaper out there to these expensive products.
