How Many Hours Of Light Do Corals Need

In particular they are regularly harvested from the islands of the Indopacific including Fiji Tonga Solomon Islands and the Great Barrier Reef.

How many hours of light do corals need. If you have algae problems or sensitive livestock then this number will change clearly but under ideal conditions this duration of lighting will allow your Zooxanthellae the maximum amount of time to undergo photosynthesis. While our eyes perceive light intensity and color uniquely based on the number of Rods and Cones the usable spectrum of light also varies depending on the photosynthetic organisms you intend to focus on. A general rule of thumb for reef tanks is between 4 and 10 watts per aquarium gallon.

This is usually the easiest method for acclimating your aquarium and corals to their new lights. Most people turn on their aquarium lights between 8 to 10 hours per day. Corals reach their peak production of photosynthesis after 6hrs.

Too much light can cause excessive algae growth. I recommend a full photoperiod of 9 hours7 hours for the core spectrum and a one-hour ramp up and a one-hour ramp down. Keep your water temperature stable around 78F.

If you running on a more conservative or lower range of PAR for your corals 12 hours is probably better. Use a high-quality reef salt mix like Instant Ocean and maintain a specific gravity of around 1025Top off the tank with moderate-to-strong LED lights and at least low-to-moderate water flow. The number of hours of light that your plant is receiving is generally not a problem if you are using natural sunlight.

They have been using LED lighting for quite some time now over our coral tanks with amazing results. However this should not be constant throughout the year. Standard aquarium water parameters are perfect for these corals.

3 Lower your daylight light intensity. Euphyllia like Hammer corals are found all over the tropical waters of the Pacific. Enhance the colors on your fish.
