Why does my Gorilla Glue Acropora encrust for months before shooting branches?

This strain often prioritizes a thick, “cemented” base in high-flow zones to stabilize itself, especially if first mounted on fresh rock. Encourage vertical growth by giving it strong, random flow and 300–400 PAR, plus a stable alkalinity of 8–9 dKH. Once the base has fully gripped and shaded edges are trimmed, you’ll usually see rapid nubbing and upward branching.

My colony’s tips look burnt while the base stays fine—what’s the likely cause?

Tip burn commonly follows an alkalinity spike in a low-nutrient setup. Confirm alk stability (daily swing <0.2 dKH), keep nitrate 2–10 ppm and phosphate 0.03–0.08 ppm, and reduce PAR by 10–15% for a week. Resume normal light once polyp extension returns. Amino dosing at night and slightly increased flow around the tips can speed recovery.

How can I preserve the signature color under LEDs without washing it out?

Target 14–18K overall spectrum with strong blue/violet (400–470 nm) and moderate white; avoid abrupt jumps in UV. Too white can mute fluorescence; too blue with ultra-low nutrients can pale tissue. Stabilize nutrients first, then fine-tune spectrum. A short evening “blue pop” period helps, but keep total photoperiod 8–10 hours and acclimate intensity over 2–3 weeks.

Why is the shaded base slowly receding while the tips look healthy?

Dense branching can starve the base of light and flow. Prune a few inner branches to open pathways, increase cross-tank turbulence, and rotate the colony slightly to expose the base. Check for pests like AEFW or red bugs if polyps stay withdrawn. An iodine dip and mild bacterial management (good skimming, fresh carbon) can halt slow tissue loss.

Acropora

Overview

Gorilla Glue Acropora Coral shows thick, knobby branches with compact corallites and a dense growth form. Classified as Acropora sp., it is a small-polyp stony branching coral that prefers strong lighting and high, turbulent water flow. It relies on symbiotic algae for energy but can accept occasional fine particulate foods, which may support growth and coloration. Place high on stable rockwork with space from aggressive neighbors, and keep parameters stable to avoid stress and tissue loss.

Care & Placement

Gorilla Glue Acropora Coral (Acropora sp.) thrives with strong, stable conditions and rewards careful husbandry. Provide high light (PAR 250–400) using LEDs or T5/LED hybrids; ramp intensity over 2–3 weeks to avoid bleaching, or use a screen for light acclimation. Deliver strong, random flow from multiple pumps to keep polyps moving and prevent detritus from settling on branches and bases. Target stable water: temperature 75–78°F (24–26°C), salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8.0–9.5 dKH (keep daily swing under 0.3), calcium 420–460 ppm, magnesium 1300–1400 ppm, nitrate 2–10 ppm, phosphate 0.02–0.08 ppm. Test weekly (more often when dialing in) and use dosing or a reactor to maintain calcium and alkalinity. Feed primarily by light; occasional small-particle foods and amino acids 1–2 times weekly can aid color and growth, but avoid overfeeding that raises nutrients.Place frags high in the tank with direct, turbulent flow; mount securely on rock with gel glue or epoxy. Allow 3–4 inches of space from other corals; Acropora is generally peaceful but can be damaged by stinging LPS and soft coral chemical warfare. Dip and quarantine new pieces to prevent pests (AEFW, red bugs). Watch for pale tissue (too much light or low nutrients) or base recession (flow dead spots, alkalinity swings). If tissue loss occurs, stabilize parameters, increase chaotic flow, check for pests, and consider fragging healthy tips. Regularly clean pumps and keep the base free of shadowing to support encrustment and long-term growth.
