Can fish sleep with blue LED?

Fish cannot sleep with blue lights on since they require entirely dark conditions for sleeping. Keeping the lights on at night will eventually impact their health, behavior, and well-being. However, blue lights can induce sleep as a means of transition between light and darkness.

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.

How much light do SPS corals need?

The general consensus is that a PAR of 450-650 umol is good to maximize the color for most of our sps. In my own experiment this summer where I set up a tank so that it would receive direct sunlight for 4-6 hours per day, during this time the light PAR on the tank reached over 1250 umol.

Do corals need more blue or white light?

corals use more of the blue white and humans use more of the white. 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.

How many hours of light do corals need?

12-13 hoursIn my opinion, for tropical corals, 12-13 hours of lighting is ideal. 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.

How much light do I need for my reef tank?

The best light to use for a coral reef aquarium will be either a metal halide/fluorescent mix or one of the new high intensity LED setups. The general rule is to use 4 to 8 watts per gallon.

Can corals get too much light?

Yes it is quite easy to expose corals to too much light. It starts with photoinhibition and can go as far as causing fatality.

How long should LED lights be on in a reef tank?

10-12 hoursIn essence, don’t let your lights run for as long as they have been. Most hobbyists run their tank lights for 10-12 hours total.

Do reef tanks need white light?

The light spectrum, or color temperature, of aquarium lighting will also alter the appearance of corals. … While different hobbyists prefer different combinations of light spectrums, a typical lighting system for a reef aquarium consists of 50% white light with a high Kelvin rating and 50% blue, actinic light.

How much UV light do corals need?

In a word, no. Corals do not need ultraviolet light. As a matter of fact, unprotected SE metal halide bulbs can burn corals quicker than you’d think possible. This article implies that penetration won’t be any more than ~10 feet in NON-turbulent water.

Do corals need red light?

It’s important to remember that algae loves red light so definitely don’t overdo it, and many of our deeper water corals like Leptoseris and Stylocoeniella, and many chalice corals will not appreciate too much red light for too long.

Does algae grow under blue light?

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.

How often should I feed my corals?

Too much food will simply go to waste. It is possible to over-feed the aquarium and stimulate algal blooms and nitrate spikes. Some aquarists feed once a month, others every day. The best approach is to carefully feed small amounts once or twice a week and see how the corals respond over several weeks.

Are LED lights good for coral?

Yes, LEDs do grow coral – just ask our experts at LiveAquaria.com! They have been using LED lighting for quite some time now over our coral tanks with amazing results. The specific spectrums provided by LED lighting can bring out colors in certain fish like you’ve never seen before.

Is t5 lighting good for corals?

Are they any good for corals? … Experts reckon the light produced may not match that of metal halides but can still be sufficient to get decent coral growth, even in the more demanding SPS corals. The size and coloration of corals from the T5-lit tanks we’ve seen is very close to that from tanks lit by metal halides.

How many watts do I need for a reef tank?

A good basic rule to follow is to provide 1 to 2 watts of lighting per gallon for fish-only aquariums, 2 to 5 watts per gallon for freshwater planted aquariums, and 4 to 8 watts per gallon for reef aquariums.

Does red light grow algae?

Algae uses red light to conduct photo synthesis. This scientific fact can be used to limit algae growth. Using only a little red light will slow algae growth. The less you use, the slower algae can grow.

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.
