Arc Fireworks Acropora is a standout SPS coral for reef keepers who love intense color and movement under blue lighting. With the right care, its branching structure and glowing tips can quickly become the focal point of your aquascape.

Placement, Flow, and Lighting

Start by placing Arc Fireworks Acropora high in the rockwork where it can receive strong, stable light and brisk flow.

• Lighting: Aim for PAR in the 250–350 range under quality LED, T5, or hybrid fixtures. Too little light leads to browning; too much, too fast can cause bleaching.
• Acclimation: Begin on a frag rack mid-level and move it higher over 1–2 weeks. Use your light’s acclimation mode if available.
• Flow: Provide strong, random flow that keeps polyps moving but not blasted. Alternate gyre or pulsing modes work well.

Water Parameters and Feeding

Arc Fireworks Acropora responds best to clean, stable water rather than constant tweaking.

• Key parameters: Alkalinity 8–9 dKH, calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 5–15 ppm, phosphate 0.03–0.08 ppm.
• Stability first: Use an auto top-off and test alkalinity at least twice a week. If you see daily swings, consider dosing 2-part or a kalkwasser solution.
• Feeding: While Acropora relies mostly on light, it benefits from:

• Light broadcast feeding of quality coral foods 1–2 times per week.
• Heavier fish feeding to keep nutrients from bottoming out.

Tip: If color fades or growth stalls, check alkalinity and nutrients before changing lights. Most problems trace back to instability, not intensity.

With strong, stable parameters, thoughtful placement, and consistent maintenance, Arc Fireworks Acropora will reward you with fast growth and vivid, firework-like coloration.
