Do Corals Need White Light
For me I prefer to have my whites on during the day In order to provide some spectrum variety for any organisms that need it.
Do corals need white light. The light is a 105 watt compact fluorescent lighting bulb with both white and blue tubes. White light is what feeds corals or rather the zooxanthellae algae in their tissue so just make sure theres plenty of it and if its too much corals will colour up further to shield themselves. Yes corals do need white light but not as much as you might think.
Fortunately there are many choices to select from. Corals usually thrive in blue light rather than pure white. The idea was to add to the ATLANTIK V4 enough infrared color to satisfy coral of all habitats.
Whereas we may shade our eyes from bright sunlight these animals have no such luxury. If the reef corals youre looking after have been collected from deeper waters of 10 and more meters 33 feet or more then set the spectrum of your LED lights at a 61 blue to cool white wavelengths at a medium intensity of around. When a coral bleaches it is not dead but it is under extreme stress and can die quickly.
Tentacles were a little skinny though. The base of the birdnest is 3 inches from the top of the water and only about 5 from the light stock CF lights. Metal halide and especially HQI lamps all emit much UV-A and must be filtered out by a glass or acrylic cover or corals face the possibility of bleaching as the Zooxanthellae cannot adjust to this light.
None or minimum whites. Mostly because aquarium lamps exaggerate the violet-blue light and make the corals glow brighter. Plus you dont get ideal conditions on every dive and dont study corals with a magnifying glass.
Often described as the best light. So what is the best light for growing SPS corals. For instance you can experiment with 70 blue.
