Fine, evenly spaced polyps give the frag a cloud-like texture, creating a calm, ethereal appearance that stands out beautifully in high-energy SPS reefs without overwhelming the palette.

🧬 Overview
The Soft Sky Tenuis Acropora is a serene, elegant SPS frag ideal for collectors who appreciate understated beauty and clean, pastel colouration. Unlike neon-focused tenuis morphs, this piece shines through its subtle gradients — from pale sky blue to soft glacier highlights — creating a soothing visual effect.
Its refined structure and gentle tones make it a perfect balancing coral in mixed SPS displays, adding harmony and sophistication.
🍽️ Care & Feeding
Fully photosynthetic, though colour clarity can be enhanced with occasional micro-feeding (Reef Roids, Coral Dust, Phytoplankton). Maintain stable alkalinity, calcium, and trace elements — particularly potassium and iron — to preserve the soft-blue chromoproteins.
📈 Optimal Parameters
| Parameter | Ideal Range |
|---|---|
| Alkalinity (dKH) | 8–9 |
| Calcium (Ca) | 430–460 ppm |
| Magnesium (Mg) | 1300–1400 ppm |
| Nitrate (NO₃) | 2–10 ppm |
| Phosphate (PO₄) | 0.02–0.08 ppm |
📍 Placement
Mount the frag high in the rockwork with strong, alternating flow. Avoid heavy shading — consistent PAR is key for maintaining the luminous, icy-blue hues.
