The 2hr Aquarist APT Sky
The 2hr Aquarist APT Sky: Discover new possibilities with SKY-boosted water. Enable shrimps and hardwater plants to thrive together with softwater plants. Replenish all vital minerals in RO/ RODI water with no negative altering of NPK, KH or pH.
If you have softwater or use RO water, then simply add 15ml per 60L. If you have hardwater or are unsure, obtain a GH reading using any common test kit. One way is to first mix APT SKY in a small container with some water and add the milky solution into the tank. Or you can simply add APT SKY powder directly into the tank. It is OK if it covers the plants.
Conventional ‘RO remineralisers’ raise GH but almost all inadvertently alter NPK values. Most add an excessive amount of Potassium, for example. This in turn interferes with optimal fertilisation. The 2hr Aquarist APT Sky adds Calcium, Magnesium, trace minerals and natural seaweed extract, in a way that uniquely leaves NPK intact.
As a GH booster, APT SKY is ~ 3X as concentrated as conventional remineralisers. Each 3.5g / 5ml per 60L adds 12ppm Calcium and 3.5ppm Magnesiumm, raising GH by 2.5 dGH. Did we mention that it is super-soluble, non-caking and just a joy to handle?
Each 3.5g / 5ml per 60L adds 12ppm Calcium and 3.5ppm Magnesium (+2.5 dGH)
Recommended: 15ml per 60L of RO/RODI water.
