What is inside each dose of APT 1 / Zero?
Each 5ml per 100L dose adds 3.8ppm Potassium (K), 0.05ppm Iron (Fe), 0.5ppm Magnesium (Mg) and additional amounts of Boron (B), Copper (Cu), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn).
The above dosage is designed to be dosed 4 times a week. So the total per week adds up to: 15.2ppm Potassium (K), 0.2ppm Iron (Fe), 1.6ppm Magnesium (Mg) and additional amounts of Boron (B), Copper (Cu), Manganese (Mn), Molybdenum (Mo) and Zinc (Zn).
APT Zero contains no nitrates and phosphates, and should be used if you have a fish population that produces adequate nitrates in the tank (specifically, If your tank measures >10ppm NO3 by end of the week with no fertilizer dosing and water change).
APT Zero can also be used to induce steep nitrate limitation in tanks, which gives the deepest reds in species such as Rotala rotundifolia and Ludwigia arcuata. This approach is usually paired with a rich substrate to prevent long term stunting due to low nitrogen levels. To this end, APT Zero can be used as a replacement for the ADA range of liquid fertilizers (Bright K neutral, Green brightly mineral and Green brightly iron) to similar effect.
