With the 2HR Aquarist APT-EI, the famous nutrient dosing approach pioneered by Tom Barr is now available in a ready-to-use concentrate that removes the guesswork from trying to recreate this powerful and sometimes elusive formula.
For EI, dose 5ml per 100L, 3 times a week. Alternatively you can dose 2ml per 100L daily. EI routines should be combined with a 50% water change every week.
Each 5ml per 100L dose adds 6ppm Potassium (K), 6ppm Nitrogen (NO3), 1.5ppm Phosphorus (PO4), 0.16ppm Iron (Fe), and additional amounts of Boron (B), Copper (Cu), Magnesium (Mg), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn).
