Why does my Banana Lokani lose its yellow and turn olive/brown under blues?

Acropora lokani is a deepwater species; its yellow pigments wash out if PAR is too low or spectrum is overly blue-heavy without enough white/cyan. Increase PAR gradually to the 180–250 range, add some 10–12K daylight channels for a few hours, and keep nutrients moderate (NO3 ~5–15 ppm, PO4 ~0.03–0.08). Avoid red/green overshoot, which can push it toward drab tones.

My Lokani shows “burnt” tips after a water change—what’s the likely cause?

Tip burn in A. lokani often follows alkalinity spikes or rapid shifts in CO2/pH. Deepwater acros are touchy about stability. Match new water’s alkalinity to within 0.2 dKH, spread dosing over multiple smaller additions, and maintain strong, alternating flow around the tips. If damage occurs, hold parameters steady; avoid large corrections and watch for RTN.

Detritus keeps settling between the blades—any tips to prevent recession there?

Lokani’s flattened branches trap fines. Use a periodic “storm” routine: once or twice weekly, baste the colony and rockwork before filtration peaks, and run a short surge of mechanical filtration. Adjust flow to create cross-currents rather than a single jet. Keep vermetid snails in check; their mucus nets amplify detritus buildup and can irritate tissue, triggering STN lines.

What night-time care changes improve polyp extension and growth?

This species extends more after lights out. Run a gentle feeding window 30–60 minutes into darkness with fine zooplankton (e.g., 100–300 µm) and modest amino dosing. Temporarily reduce return flow slightly to keep food suspended without settling on blades, then restore normal flow. Don’t overfeed—excess organics fuel film algae on the plate surfaces and stress tissue.

Acropora SPS

Overview

Banana Lokani Acropora Coral shows bright yellow to green branches with smooth axial tips. Acropora lokani is a branching small-polyp stony coral requiring strong light and moderate to strong, turbulent water flow. It relies mainly on symbiotic algae for energy but can benefit from occasional small particulate foods, which may support growth and maintain color. Place high on stable rockwork with space from aggressive neighbors, and keep parameters stable to prevent tissue loss.

Care & Placement

Banana Lokani Acropora Coral (Acropora lokani) thrives on stability and moderate conditions typical of deepwater acros. Provide moderate light at 150–250 PAR with a slow 2–3 week acclimation to prevent bleaching; start lower and increase intensity or exposure time gradually. Use strong, indirect, and random flow to keep tissue clean and prevent detritus buildup without blasting the polyps. Maintain 24–26°C (75–79°F), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 7.5–8.5 dKH, calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, and phosphate 0.02–0.08 ppm. Test weekly with reliable kits and track alkalinity daily when new; consider periodic ICP testing. Feed small-particle coral foods or amino acids 1–2 times weekly; do not overfeed.Place frags mid to lower rockwork with room for horizontal/tabling growth; give 3–4 inches of space from neighbors. Avoid contact with aggressive LPS and keep away from direct sandbed turbulence. Mount securely on stable rock to prevent shading and falls. Temperament is generally calm, but it can overgrow slower species under good conditions. Acclimate via dip and quarantine to avoid Acropora-eating pests (AEFW, red bugs). Common issues: bleaching from sudden high light or ultra-low nutrients; browning from low light or high nutrients; tissue recession from alkalinity swings or poor flow. Correct by restoring stable parameters, improving indirect flow, and adjusting light slowly.
