Do LED lights cause more algae in an aquarium?

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.
Do blue LED lights cause algae?
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.

If you have chosen nothing but “Easy” plants, 10-20 lumen (0.25 to 0.5 watts) per litre is adequate. For “Medium” plants, we recommend 20-40 lumen (0.5 to 1 watts) per litre, while “Advanced” plants require more than 40 lumens (1 watt) per litre.
Can a fish tank have too much light?

Is too much light bad for aquarium plants?
If there is an infinite amount of light, there will be a limit as to how much CO2 and nutrients the plants can use up in a given time. Algae will then start to feed off of the excess. Everything needs to be in balance in order to have an algae free planted aquarium. That’s why more light is not always better.
What color light is best for fish?
Red, blue and green LEDs are in popular use for standard aquarium lighting since these light temperatures greatly enhance the colors of the objects inside the aquarium.

Can too many plants kill fish?
“An overabundance of aquatic plants can strain a pond’s ecosystem and potentially lead to a fish kill,” said Pattillo. “During daylight hours, plants produce oxygen and raise the water pH, yet at the same time the plants respire, removing oxygen and adding carbon dioxide and lowering the pH.
Do fish need lights off at night?
The fish do not need light and it is best that your turn it off during the night. Leaving the light on can cause stress to fish as they need a period of darkness to sleep. Too much light will cause algae to rapidly grow and make your tank look dirty. So the short answer is no, do not leave your lights on.
