Hi!
I would just like to know, as every ''reddish'' plant turns green in my tank due to the 40ppm of added nitrogen, how low should no3 get so that my recently added rotala and my evergreen limnophilla aromatica turn red?
Some technicalities:
Light- 2x45wt5 ,
Fotoperiod:9h
Filtration: 2xinternal filter (2x600lit-h)
Flow pumps: Atman 2x500lit-h , 1x350lit-h
Overall flow: aprox 2500lit-h
CO2: 20kg pressurised tank , fabco nv
CO2 level: DC is yellow , CO2 goes through an airstone and into the three Atman flow pumps and spreads across the aquarium , co2 is set as high as it goes , if i turn it up higher my fish start to pass away.
