Coral reefs are under increasing pressure from warming waters, pollution, and local stressors. One response is coral farming—growing corals in controlled conditions and using them for restoration, rehabilitation, and responsible display.

In-house coral production helps us shorten timelines and maintain closer oversight of each batch’s health, growth, and genetic background. Rather than treating coral as an off-the-shelf product, we treat it like a living system: monitored daily, adjusted as conditions change, and documented end to end.

Starting with broodstock and genetics

Our process begins with selecting parent colonies (broodstock) from established source populations. We prioritize genetic diversity where possible and keep clear records of lineage, collection context, and propagation method. This approach supports long-term resilience goals, especially when corals are intended for restoration rather than short-term display.

Before any fragments move into nursery space, they undergo an intake assessment. We screen for visible disease signs, structural fragility, and stress response, then acclimate them gradually to our system parameters.

Nursery first: stable water, low stress

Once fragments are ready, they enter a nursery phase designed to protect them during the most sensitive growth period. Conditions are kept consistent: stable temperature, controlled salinity, appropriate alkalinity and calcium levels, and carefully managed nutrient levels to avoid both starvation and nuisance algae.

We also focus on flow patterns and light schedules that match each coral’s needs. Small changes in lighting intensity and water movement can strongly affect polyp extension and tissue health, so we tune settings to species-specific requirements and track outcomes.

Feeding and maintenance tailored to species

While many corals rely primarily on photosynthesis, supplemental care can improve growth for certain types—especially when fragments are still establishing tissue. Our husbandry routines include targeted feeding when appropriate, along with manual cleaning steps that reduce biofouling on plugs, bases, and frag racks.

Health checks are frequent. We monitor coloration, polyp behavior, tissue thickness, and signs of common stressors such as tissue recession, rapid algal takeover, and localized bleaching. When issues appear, we isolate affected colonies, adjust parameters, and document interventions rather than treating every tank the same way.

Frag growth to tank transfer

As colonies grow, they move through a staged “farm-to-tank” timeline. We track growth rates and frag stability, and we only transfer corals when they demonstrate consistent recovery and stable expansion. The goal is to avoid moving corals prematurely—since early transfers can lead to setbacks and higher losses.

Transfers also include a controlled acclimation process so corals adapt to new flow regimes, light intensity, and water chemistry. Each move is recorded with date stamps and observations, which helps refine husbandry protocols over time.

What this in-house model changes

Running coral production in-house changes the quality of the supply chain. Because we control the full workflow—from intake to nursery to transfer—we can respond faster to program needs, maintain consistency between batches, and reduce the stress that comes from long shipping timelines.

Equally important, in-house systems improve traceability. For restoration-focused projects, documented lineage and propagation history matter. For display programs, consistent husbandry helps maintain animal welfare and supports more reliable long-term survival.

Coral farming is not a single technique; it’s an ongoing commitment to biology, water chemistry, and careful observation. By growing corals in-house, we aim to make that commitment visible—so every “tank-ready” fragment arrives as a healthy, well-adapted living organism, not a mystery shipment.
