Are the fertilizers that we used for the Aquatic plants just like
the normal ones we would use in a home garden? Or is it diffrent?
What about the types?, could you guys get me started?
Ummmm..... Do fertilizers harm your fish?, even with the most sensitive
of fish and snails?

How do they work?, And any other information would be great thanks :)

Hi Black oranda,

garden plants and aquarium plants need more less the same elements.
They are, N, P, K, Ca, Mg, S, C, Mn, Fe, Zn, Cu, B, Mo, and Cl. The only difference is in what chemicals we use.

For example, to supply N to garden plants we can use Ammonium nitrate NH4NO3. For aquarium we can not do that because NH4 is bad for fish and also increases algae growth. So we use KNO3 and CaNO3. Other than NH4NO3, we can use the same fertilizer for garden and aquarium. Only the mixed concentrations and rations are different.

N - KNO3
P - KH2PO4
K - K2SO4
Ca - CaCl2, CaSO4, CaCO3
Mg - MgSO4
S - K2SO4, MgSO4, CaSO4
Cl - CaCl2
C - CO2
Mn, Fe, Zn, Cu, B, Mo - TE (Trace Elements Mix)

Aquarium fertilization developed from hydroponics industry.
