How long should settlers be left undisturbed to begin skeletal deposition?

The duration for which settlers should be left undisturbed to initiate skeletal deposition typically falls within the range of 1 to 2 weeks. During this period, coral larvae or settlers establish a firm attachment to their substrate, allowing for the physiological processes necessary for skeletal growth to commence. This is a critical phase in coral development, as it facilitates the transition from a lax larval form to a more permanent, structurally robust organism capable of forming skeletons.

Allowing the settlers this timeframe minimizes disturbances that could disrupt their attachment and the early stages of growth. Environmental factors, such as water quality and flow, as well as biological interactions, positively influence the initial phases of skeletal development, which tend to require this optimal period for successful establishment. Therefore, the choice of 1-2 weeks reflects the latest understanding of optimal conditions for coral settlement and skeletal development.
