First Due Aquatic Rescue Informational Guide For SPS

Small Polyp Stony (SPS) corals are the foundation builders of natural reef structures, known for their dense calcium carbonate skeletons and vibrant coloration. These corals belong to the order Scleractinia and are characterized by their six-fold symmetry—meaning their tentacles typically appear in sets of six or multiples thereof.

SPS corals are ideal for experienced reef keepers who prioritize water quality, stability, and lighting precision. They require strong, turbulent water flow and high-intensity lighting to thrive. Because of their sensitivity, maintaining consistent levels of calcium, alkalinity, and magnesium is critical for healthy growth and vibrant coloration.

It's important to note that not all SPS corals have the same care requirements. For example, Acropora and Seriatoporamay both fall under the SPS umbrella, but their tolerance to environmental changes can vary significantly. We recommend researching individual species to match the needs of your reef system.

Whether you're looking to build a high-energy SPS-dominated reef or add structural diversity to an established system, this collection offers a curated selection of premium SPS corals grown and maintained with expert care.
