Description

APT Sky by 2HR Aquarist is a GH booster designed for planted aquariums using RO or RODI water. It replenishes essential minerals like calcium and magnesium without negatively altering KH, pH, or disrupting your fertilizer regimen, making it easy to create stable water conditions for both aquatic plants and freshwater shrimp. Ideal for aquascapers growing demanding softwater plants or keeping shrimp in mineral-controlled environments, APT SKY dissolves quickly and delivers precise, consistent remineralization.

Unlike traditional remineralizers that can impact carbonate hardness, APT SKY raises only general hardness (GH), allowing you to fine-tune water parameters while maintaining optimal conditions for planted aquariums. It’s an excellent choice for high-tech aquascapes, Caridina shrimp tanks, and any setup relying on RO or RODI water for maximum control over water chemistry.

Key Features and Important Notes

Specifically formulated to increase general hardness (GH) without raising carbonate hardness (KH)

Replenishes essential minerals, including calcium and magnesium, for healthy plant and shrimp growth

Dissolves quickly for fast, even remineralization

Suitable for freshwater shrimp, including Caridina species that thrive in soft, mineral-controlled water
