Sorry but a lot moe information about your system is needed. Coral growth is significantly more than just lighting (which includes intensity and spectrum). Variables include species and genotype, age, feeding (this in itself includes feeding or not feeding particulate and/or dissolved organic and/or inorganic nitrogen and phosphorus), zooxantheallae clade and density, water flow (more is not always better), substrate, and tank mates can play a role as the different taxanomic groups moderate different bacteria groups in a reef ecosystem (some beneficial for corals some not). And keep in mind trying to get corals to grwo fast aslo risks compramising their health. Here's some links if you're interested in reading more:
Developing an optimal heterotrophic feeding regime has the potential to improve captive coral growth and health. This study evaluated the efficacy of three exogenous diets: Artemia nauplii (ART), a commercially available coral diet (Reef Roids) (RR), and a novel, micro-bound diet (ATF), against...
Improved coral cultivation will facilitate the reduction of wild harvesting, reef restoration, preservation of biodiversity, and the use of corals as model experimental organisms. In this study, we examine species-specific responses in growth and
With the continued and unprecedented decline of coral reefs worldwide, evaluating the factors that contribute to coral demise is of critical importance. As coral cover declines, macroalgae are becoming more common on tropical reefs. Interactions between these macroalgae and corals may alter the...
New From our friends over at the Burkepile Lab at Florida International University - It's been communicated many times that nutrient pollution of the oceans can affect the performance of various coral species. To date, the results have been varied…researchers find different responses, but they...
Heterotrophic feeding in newly-settled coral planulae can potentially improve survivorship and accelerate early development in some species; however, an optimal diet to facilitate this does not currently exist. This study evaluated the efficacy of three heterotrophic feeding regimes (enriched...
Global decline of coral reefs has led to a widespread adoption of asexual propagation techniques for coral restoration, whereby coral colonies are fragmented and allowed to re-grow before being returned to the reef. While this approach has become increasingly popular and successful, many...
Regeneration of artificially induced lesions was monitored in nubbins of the branching coral Acropora muricata at two reef-flat sites representing contrasting environments at Réunion Island (21°07′S, 55°32′E). Growth ...
In this study, two factorial experiments were used to investigate the role of tissue age in affecting the phenotypic expression of calcification in scleractinian corals. Both experiments tested whether calcification was altered by tissue age and whether corals of different ages exploit...
Most coral reefs have recently experienced acute changes in benthic community structure, generally involving dominance shifts from slow-growing hard corals to fast-growing benthic invertebrates and fleshy photosynthesizers. Besides overfishing, increased nutrification and sedimentation are...
