To use fertilizer or not?

[Canuck]

Doesn't DW use mineralized top soil?

She originally just suggested regular top soil.

Wouldn't that count as a fertilizer?

He did say he doen't use "chemical" fertilizers.



I use ferts on all my tanks (CO2 and non CO2), it eliminates the possibility of deficiency problems which generally lead to algae.

That said the need for chemical fertilizers is dependent on the amount of light, which dictates the amount of plant growth. Fish cannot generate enough nutrients for plants in a high light environment.

I think you're asking the wrong question. Plants can't grow without fertilizer, its just a matter of how its delivered, through the fish, from soil, or by chemicals.
