From Red Sea website:
It is widely accepted that there is a narrow spectrum of water conditions that are suitable for keeping corals. Red Sea’s research into the long term physiological demands of SPS, LPS & Soft Corals in the reef aquarium has shown that enhanced coloration and accelerated growth require significantly different water conditions. It is relatively easy to maintain the conditions for accelerated coral growth. Maintaining the conditions for enhanced coloration is more demanding in that it requires a higher level of attention to the water parameters. It is theoretically possible but not recommended to achieve both accelerated growth and advanced coloration simultaneously as the system will always be on the edge of instability. The complete Reef Care Program provides advanced reef keeping solutions for all levels of hobbyists, with detailed instructions on achieving optimal water parameters for all types of reef aquarium.
Recommended water parameters for accelerated coral growth
• Algae nutrient levels of 1 – 2 ppm nitrate and 0.1 ppm phosphate; to maintain a relatively high population of Zooxanthellae that will provide enough energy to the corals for growth.
• Boosted and balanced levels of the Foundation Elements [Alkalinity 12.6dKH / 4.5meq/L, Ca 465ppm, Mg 1390ppm] to properly utilize all of the extra energy
• Availability of the minor and trace elements (Coral Colors) taken up by the corals during growth [I2 0.06ppm, K 410ppm, Fe 0.15ppm]
• Sufficient coral nutrients (Reef Energy) to supplement the energy supplied by the Zooxanthellae [2ml of Reef Energy A & B per 100Liter/25gal]
Recommended water parameters for enhanced coloration
• Algae nutrient levels of 0.25 ppm nitrate and 0.02 ppm phosphate; to maintain a reduced level of Zooxanthellae, reducing the brownish tint of the corals and inducing the protection response of enhanced coloration.
• Reduced levels of the Foundation Elements [Alkalinity 8.2dKH / 2.9meq/L, Ca 430ppm, Mg 1310ppm]to lower the energy demand from coral growth
• Availability of the minor and trace elements (Coral Colors) used in the soft tissue for increased coloration [I2 0.06ppm, K 380ppm, Fe 0.15ppm]
• Increased coral nutrients (Reef Energy) to provide the additional energy that the coral needs to receive from the environment [4ml of Reef Energy A & B per 100Liter/25gal]
Edit: I started using their reef care program on my tank and I am attempting to see what results I get in creating a very colorful tank. I have been pleased so far with the algae control over the two weeks I have starting dosing (no3 po4 x). It has helped control my nitrate and phosphate levels and I have been able to feed more. I looked to change the salt because when I do a water change my levels climb higher than desired. The Red Sea Coral Pro Salt has a very high calcium and magnesium level.
