Types of fertilizers that require dirt and not aquarium substrate?
Are there types of fertilizers that require dirt and not aquarium substrate(eco-complete in my case)? Perhaps there is some kind of microbacteria that is required to convert one of the chemicals into plant food?
I know that in hydroponics you have to use special liquid fertilizer and you can't just throw miracle grow in it.
For example, I have accidentally bought Tetra POND LilyGro.
" Derived from Ammonium phosphate, Potassium nitrate, UREA Formaldehyde, Magananese Sulfate, Ferric Sulfate, Zinc Sulfate, Copper Sulfate, Boric acid, Sodium Molybdate.
Total Nitrogen (N), 10%
Ammoniacal Nitrogen, 5.5%
Nitrate Nitrogen, 2.4%
Water Soluble Nitrogen, 1.5%
Urea Nitrogen, 0.6%
Available Phosphate (P2O5), 14%
Soluble Potash K2O, 8%
Boron (B), 0.02%
Copper (Cu), 0.05%
Water Soluble Copper (Cu), 0.05%
Iron (Fe), 0.11%
Water Soluble Iron (Fe), 0.11%
Manganese (Mn), 0.12%
Water Soluble Manganese (Mn), 0.12%
Molybdenum (Mo), 0.0006%
Zinc (Zn), 0.07%
Water Soluble Zinc (Zn), 0.07%
Is there a reason this would work in a pond but not in an aquarium? Do any of these things require dirt vs Eco-complete substrate( Crushed lava rock)?
