Hi,
The EI (Estimative Index of Dosing) method says that for a 20 gallons with 5.5 watts/gal the dosing will be:
1/4 teaspoon of KNO3 4x a week (every other day)
1/16” teaspoon of KH2PO4 4x a week (every other day)
Traces added on off days as the macro nutrients, so 3x a week, 5mls each time.
Using the Chuck's calculator that will be:
KNO3 = 11.29ppm Nitrate - 7.13ppm Potassium
KH2PO4 = 2.66ppm Phosphate
Now, If I translate that to my 77 gal tank with 2.02 watts/gal and fluorite+eco-complete+gravel substrate, the dosing will be:
1 teaspoon of KNO3 (11.8ppm Nitrate - 7.45ppm Potassium)
1/4 teaspoon of KH2PO4 (2.88ppm Phosphate)
Traces 15mls of Flourish Trace™.
Am I doing the calculations right or am I forgetting something? If my level of light is much lower than Barr's setup should I dose macros just 2 times per week and traces once a week?
My tank is going to be medium to heavy planted with no fish at the beginning just shrimps (at least until I get used to the plants or they get used to me )
Thanks for any help
