Maintenance
This is how my nutrition maintenance looks right now and has been for about four weeks.
A large water change on Saturday morning.
Nutrition concentration after the water change including added nutrition and tap water levels:
FE = 0.25ppm
NO3 = 20ppm
PO4 = 1.46ppm
K = 20ppm
Mg = 4.5ppm
(Ca = 24ppm) only by tap
Daily concentration increase Sunday – Friday:
FE = 0.13ppm
NO3 = 1.9ppm
PO4 = 0.3ppm
K = 1.5ppm
I have checked the levels during the week and it seems to be very stable through the week.
The growth is very good and everything seems to be working great.
