APT Sky Plus Booster

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 without negatively altering NPK. Moderately raises KH to ~2 dKH and pH to 7.2~7.6

Each 3.5g / 5ml per 60L adds 9ppm Ca and 2.5ppm Mg (+1.8dGH, +0.5 dKH)

Recommended: 15ml per 60L of RO/RODI water.

*To grow softwater plants, RO/RODI water recommended if tap water measures >2 dKH

APT SKYPLUS 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). It moderately raises KH to ~2dKH, within the band still favoured by most commercial aquatic plants.
