Dennis' post just leads me to ask something I've been wondering about lately. Someone please correct me if I'm wrong and I'm not bashing anyone's methods, just curious. Amano's tank parameters are < 1ppm NO3 and PO4 and he says sufficient NO3 and PO4 are generated in a planted tank. The ADA ferts seem to be geared towards adding K and traces back which, in his view, are depleted in a planted tank. His lighting also seems to be a bit over 2 wpg on his tanks. So I guess what I'm wondering is #1- is EI geared toward higher light setups, #2- are NO3 levels of 10-20 ppm necessary, # 3 - what role if any does KH play in any of this?
I've been using EI very successfully for the last year but after reading some posts regarding lower NO3 levels and noticing Amano's levels it has me wondering. We have very soft water, KH and GH are both <1 out of the tap. I plan on beginning a gradual decrease in the amount of NO3 and PO4 I'm dosing while continuing with K, Mg, Ca and traces at current levels and see where it goes. |
