2Hr Aquarist APT Sky Plus (150g)

Description

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

WHY APT SKY PLUS?
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.

2Hr Aquarist APT Sky Plus (150g) for Singapore Shrimp and Plant Tanks

APT Sky Plus is a remineraliser built to solve a common dilemma for hobbyists running RO or RODI water: how to add the calcium and magnesium that shrimp and harder-water plants need while keeping NPK fertilisation under your own control. By replenishing minerals and moderately lifting GH and KH, it lets you create a stable base where shrimp and a wider range of plants can share one tank more comfortably than they would in untreated water.

For Singapore keepers this is most useful when starting from RO or RODI rather than our soft, chloraminated tap supply, which already carries some hardness and chloramine you would rather not build a sensitive shrimp tank on. Dose per the label against your measured GH and KH, retest after mixing, and add minerals to fresh change water before it goes into the tank for consistency.
