OK - I'm trying to make sense of the dosing for a low tech tank. Tom Barr suggests this once per week per 20g:
1/4 Teaspoon of Seachem Equilibrium (for traces and Calcium + Magnesium
1/8 Teaspoon of KNO3 (Potassium Nitrate)
1/32 Teaspoon of KH2PO4
According to the fertilator from aquaticplantcentral this will add:
NO3 (nitrate): 5.27ppm
PO4 (phosphate): 1.61ppm
K (potassium): 7.42ppm
Ca (calcium): 1.42ppm
Mg (magnesium) .42ppm
Fe (iron): .02ppm
If correct, it’s going to have to use the following to get nearly the same ppm dosing rate for each nutrient:
Flourish Nitrogen: 15ml
Flourish Phosphorus: 70ml
Flourish Potassium: 10ml
Flourish Iron: 0ml
Seachem Equilibrium: 0.6875 tsp
However, in Tom's discussions, he mentions that dosing low tech would be approximately 10% of recommended levels. Looking at the suggested levels on the fertilator, this would be more like:
Flourish Nitrogen: 6ml
Flourish Phosphorus: 9ml
Flourish Potassium: 0ml
Flourish Iron: 0ml
Seachem Equilibrium: 0.6875 tsp
Which yields:
NO3 (nitrate): 1.9ppm
PO4 (phosphate): 0.19ppm
K (potassium): 4ppm
Ca (calcium): 1.42ppm
Mg (magnesium) .42ppm
Fe (iron): .02ppm
So I am confused and looking for advice. What is the target nutrient level in ppm? Are the amounts in the fertilator correct? Looking for advice to get started on a dosing routine.
I also added flourish tabs into the gravel bed.
