- pH: 8.1-8.4

- Salinity: 35ppt

- Alkalinity: 8-12 dKH

- Calcium: 400-450 ppm

- Magnesium: 1200-1350 ppm

2. Lighting:

- Moderate to high lighting (PAR 100-200)

- A combination of blue and white LEDs is recommended

- Ensure adequate flow to prevent algae growth on the coral's surface

3. Flow:

- Moderate to strong flow

- Use a powerhead or wavemaker to create a gentle current
