2Hr Aquarist APT Sky replenishes all vital minerals in RO or osmosis water without negative changes in NPK, KH or pH. Having the ideal KH and GH in the aquarium is essential for growing aquarium plants. If these values become too high, some plants will have difficulty growing.
Ideal values in a plant aquarium are at a dGH of 5-7. When keeping more difficult plant species, a KH value of 2 or even less is desirable. In most cases, tap water is too hard and osmosis water is a requirement. With APT Sky the dGH is increased to the desired value without increasing the KH. Every 5ml (3.5gr) per 60L adds 12ppm calcium and 3.5ppm magnesium (+2.5 dGH).
Recommended: 15ml per 60L RO/RODI water. Regularly measure the dGH value of the water to check whether there is too much or too little Calcium and Magnesium.
APT SKY solves a complex issue of increasing water hardness (particularly as a GH booster), without changing NPK values (which interfere with calibrated fertilizer ratios) and KH (where higher values are not preferred by most commercial aquatic plants).
