Discover new possibilities with SKY-boosted water. Enables shrimps and hardwater plants to thrive together with softwater plants*. Replenishes all vital minerals in RO/ RODI water with no negative altering of NPK, KH or pH. Each 3.5g / 5ml per 60L adds 12ppm Calcium and 3.5ppm Magnesium (+2.5 dGH) Recommended: 15ml per 60L of RO/RODI water. APT SKY resolves the key conundrum of how to increase water hardness (specifically as a GH booster) without altering NPK values (which interfere with the calibrated ratios of fertilisers) and KH (where higher values are not favoured by most commercial aquatic plants).
