      LED's and SPS Growth

      Below are sequential photos of my tank, specifically the ASD Rainbow Milli that I received from Atkinsman In October of last year.

      From October through December the LEDs over the top were 6 Cree 3w Whites and 6 Cree 3w Royal Blues.

      In late December I added 5 3w Red and 5 3w Turquoise LEDs, and the photos speak for themselves! Corals went from encrusting to branching VERY quickly with enhanced growth. Calcium/Alk supplements to the tank increased by 75%.

      Two weeks ago, I added 4 Hyper UV and 2 True UV bulbs to the array. Slight color shift noticed with the eye…will see how growth is affected. All the groups of lights are on separate manual dimmers and I hope to have someone over to do par readings with different combinations. Right now everything is up full, and most all LEDs are using optics or are manufactured with 80 degree lenses.

      Here are the dated Picts…
