How to calculate the amount of acid that needs to be added to nutrient solutions?

Neutralize 100 mg/l of alkalinity (HCO3-) per 1000 liters of irrigation water:

Acid product per 1000 l of irrigation water per 100 l stock solution with 1:100 dilution
Phosphoric acid 85% 0,10 liter 1.0 liter
Phosphoric acid 75% 0.125 liters 1.25 liters
Magnofoss 0,17 liter 1.7 liters
Nitric acid 62% 0,12 liter 1.2 liters
Nitric acid 53% 0.145 liters 1.45 liters

Use Effect+ to neutralize alkalinity (HCO3-) in spray liquid:

To reduce alkalinity by 100 mg/l, you need to add 12 ml of Effect+ per 100 liters of spray liquid.

To maintain an alkalinity of 50 mg/l in the raw water, add the following amount of Effect+ (ml/100 l spray liquid):

Alkalinity Quantity of Effect+ (ml/100 l)
50 0
100 6
150 12
200 18
250 24
300 31
350 37
