JF Chemical Reaction Chalice Coral
Overview
JF Chemical Reaction Chalice Coral shows a flat, plating surface with raised eyes and contrasting coloration. Classified as Echinophyllia sp., it is a stony chalice coral that grows as encrusting plates; it prefers moderate light and low to moderate, indirect flow. It is photosynthetic via symbiotic algae but benefits from occasional small meaty foods at night, which can improve growth and maintain color. Place on a stable rock or sandbed with space around it, as sweeper tentacles can sting nearby corals.

Frequently Asked Questions
About the JF Chemical Reaction Chalice Coral
-
Why does my JF Chemical Reaction chalice lose neon rim/eye contrast after a few weeks?
This morph is light- and nutrient-sensitive. Intense PAR (>150–200) washes pigments, while ultra-low nitrate/phosphate mutes eyes. Aim for 80–150 PAR, strong blue/UV spectrum, and moderate nutrients (NO3 5–15 ppm, PO4 0.03–0.08). Avoid rapid alkalinity swings; chalices fade or recede at unstable dKH. Trace balance (especially iodine and potassium) supports rim color; dose only if test kits confirm deficit. -
The edges are receding inward at night—what’s causing it and how do I stop it?
Nighttime mesenterial filament wars or vermetid mucus irritation are common triggers. Give 3–4 inches clearance down-current from aggressive neighbors, break vermetid tubes, and increase random but gentle flow. Verify no nipping from dwarf angels. Stabilize alkalinity 8–9 dKH and raise nutrients slightly if ultra-lean. An iodine dip and clean frag plug can halt bacterial edge melt. -
It won’t take food during the day—am I underfeeding?
Echinophyllia extend feeders mostly after lights out. Try a 15–30 minute blue/actinic phase and a tiny amino or food “teaser,” then target mysis/roe/reef roids gently. Feed 1–2x weekly. If mouths stay tight, check salinity and pH stability; stressed chalices won’t feed. Avoid blasting; small, sticky portions on the eyes work best. -
Can I let it grow onto the main rockwork for a plating look?
It will encrust and plate over contours, but plan ahead. Once it fuses to large rock, removal is difficult and collateral damage likely. Isolate on a “chalice island” or a removable shelf. Keep the growing edge from touching other LPS/zoas; this morph throws potent filaments. Maintain space on all sides to guide growth and simplify pruning.
