Lighting
SPS commonly prefer moderate-to-high light, but every coral should be acclimated before reaching its final position.
SPS care
Stability first. Intensity second.
Small-polyp stony corals thrive when mature reef systems deliver consistent chemistry, purposeful flow, and carefully acclimated light.
Flow
Provide strong, varied, indirect flow that reaches the entire colony without creating a constant jet.
Chemistry
Keep alkalinity, nutrients, calcium, magnesium, salinity, and temperature consistent. Avoid rapid corrections.
Observation
Watch polyp extension, coloration, and growth tips. Changes are signals to investigate, not reasons to react abruptly.
