APT Estimative Index - 1000ml
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.
Dose 5ml per 100L three times a week or 2ml per 100L daily.
