but take that with a grain of salt, corals can utilize a lot of the light spectrum, however blue light is more useful then white light..

Does Blue Light promote algae growth?

Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria. Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals.

Can I leave blue light on in fish tank at night?

Can Fish Sleep in Blue Light? A blue ambient light in an aquarium is meant to mimic moonlight. They are a great addition to any tank as they don’t affect the day and night cycle of the fish or plants and don’t contribute to the growth of algae.

How many hours of light should a reef tank have?

Many reef aquarists, especially the beginners, get confused about how many hours of LED light they need to supply for their reef tanks. It is recommended to ensure a photoperiod of 9 hours where 7 hours will be under the core spectrum and 1-hour of ramp-up and 1-hour of the ramp-down period.

How long can Corals go without light?

OP, seven days is fine. Corals have evolved for millions of years to withstand long stretches withno or very little light due to storms.

Do corals need red and green light?

So basically when it comes down to it your coral will thrive under any of these: Red light, white light, green light, blue light, UV light…. or any combination.

Can I leave the moonlights on all night?

Total darkness is definitely not harmful to fish and losing some color in total darkness is normal. I have my blue LED moonlights set to be on for 2 hours after the main lights go off. This alows me to observe the activity of my nocturnal catfish. However, it’s healthy for fish to have some period of total darkness.

How much light does a coral need?

Over the years hobbyists have discussed crude measurements of the amount of light corals need to thrive. Most successful reef aquarists will use about 6-8 watts of light per gallon of tank water, more in deeper tanks and less in shallower tanks.

Do corals need light at night?

The majority of coral growth occurs during the day as a byproduct of photosynthesis which is a means to regulate ph inside the coral tissue. Very little calcification occurs during the night. Complete darkness is not necessary, nor natural.

How long can Corals stay out water?

If working completely submerged not practical, 10-15 minutes of exposure to air probably won’t be a problem for *most* corals (apart from some LPS with heavy water filled tissue) if they are kept out of extreme heat and strong light.

How many hours of light does an anemone need?

Unless you have Metal Halide or maybe T5 lighting the anemone wont stay healthy in the long run. I would keep the lights on for around 12 hours a day and 12 hours off. The anemone will inflate and deflate randomly. When they deflate for a long period (days) is when you know there is a problem with it.

Are blue LED lights bad for fish?

Do fish like blue light at night? They do! Blue LED lighting can be used to mark the transition between dawn and dusk, as well as mimic moonlight. Don’t worry about ambient blue light affecting your fish’s night-and-day cycle and the growth of plants, corals, and algae.

What color light do corals need?

Fluorescent Pigments Due to its underwater environment, coral has adapted to grow best using light from the blue end of the spectrum in photosynthesis, and because of this, most fluorescent coral will glow green or red.

What color light is best for coral growth?

As water depth increases, the reds, oranges, and yellows are gradually filtered out, leaving more blue light. For optimal coral growth, you will generally want a full spectrum of light that includes some reds, oranges, and yellows, but that is heavier towards the blue range.

Is blue light better for corals?

All blue leds at a high enough PAR will keep corals healthy and they will grow. But they may not be as colorful as they will be if they get other wavelengths of light. The zoanthellae (algae) that our corals grow inside the polyps use mostly blue light and a little red for photosynthesis.

Should I add coral or fish first?

For corals vs. fish, it comes down to which is more sensitive. Do the hardiest first, then slowly add the more sensitive animals over a couple months (being wary of adding any overly aggressive fish early). So for example, if you want a mandarin and mushrooms, go with the mushrooms first.
