Is it okay to leave the LED light on in a fish tank?

Is it good to have multicolored LED lighting in an aquarium? LEDs are now available in a multitude of color spectrums and combinations, so don't get stuck on one or two colors. Do corals grow better under LED lighting? 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. Should you submerge LEDs? Even though an LED may be water resistant or waterproof, it doesn't mean it's designed to be submerged and used underwater. Can salt or mineral deposits harm LEDs in aquariums? Salt and minerals deposits cause corrosion and really damage the heat sink and LEDs. Can LEDs harm your corals? LED lights can be very intense and sudden changes in light brightness can cause some corals to expel their zooxanthellae and "burn" or "bleach white."

Most fish and aquarium plants thrive when their fish tank lights are left on for ten to twelve hours a day. LED fish tank lighting is more energy efficient, costing about 80% less than older fluorescent lights and is preferable for fish health since it doesn't give off potentially harmful heat that can alter the condition of the water. Is it OK to Put LED Lights in a Fish Tank? LED lights are a great way to boost aquascaping plant growth, keep your fish happy, and promote beneficial oxygen levels aquatic species need to thrive.

What Colour Light is Best for Aquarium Fish? Fish tank lighting normally looks most effective in white or green; natural colours bring out the organic tones of your tank and aquarium plants, although blue lighting can also work well for species such as guppies.

Does LED Light Cause Algae in Fish Tank Environments? Theoretically, aquarium lights can help algae grow; however, healthy algae growth is important for a natural aquarium environment, and the presence of plants will eliminate excessive blooms. If you have an overgrowth of algae, you likely require an Aquarium Treatment to rebalance the nutrients in your water; an efficient set of aquarium LED lights will not cause too much algae.

Most fish need around 12 hours of daylight and 12 hours of darkness each day. However, you don’t need to turn your fish tank light on for a full 12 hours every day, as natural light should be bright enough to fill a few of these hours. Instead, fishkeepers should create cycles of light so their fish can distinguish between day and night. Therefore, we recommend leaving your fish tank light on for 8–10 hours a day. It’s fine to experiment with these hours to monitor how much algae growth you get in your fish tank and adjust accordingly. Don’t leave your fish tank light on for longer than this or your fish will struggle to find their rest period.
