Discover new possibilities with SKY-boosted water.
Enable shrimps and hardwater plants to thrive together with softwater plants*.

Each 3.5g / 5ml per 60L adds 12ppm Calcium and 3.5ppm Magnesium (+2.5 dGH)
Recommended: 15ml per 60L of RO/RODI water.
*To grow softwater plants, RO/RODI water recommended if tap water measures >2 dKH
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).
