*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).
