Do LED lights cause algae growth in aquariums?

Even old mercury lights were never a problem with growing algae. If algae can grow, it will grow under almost any light at all. More common with LED is that they get weaker over time. Little problem since most don't run them at 100% and can just turn them up a bit. LEDs do degrade in a non linear fashion. Likely not your lights though. Might be time to remove the rock and siphon the sandbed or pull it out and rinse it.

2. Lighting. The type of lighting you are using can greatly affect the growth of nuisance algae in a system. Lighting that has a high amount of green and yellow can increase nuisance algae growth. Orphek LED systems do not use LEDs that promote nuisance algae growth.
3. Photoperiod. Length of photoperiod can also affect growth of nuisance algae. For reef set ups a photoperiod of no longer than 10-14 hours should be used. For fish only, 6-10 hours.
4. Water Changes. A 10% weekly water change is recommended. Most aquarists are not inclined to do this so you can substitute with a 20% change every two weeks. Water changes dilute and remove dissolved organic compounds in the water that promote nuisance algae growth.
6. Filter Media. You can improve your filtrations system by using media that will help purify and remove dissolved organics from your water. These media include phosphate removers and a good grade of activated carbon.
8. UV/Ozone. UV sterilizers and ozone generators can increase the ORP level in systems creating a healthier environment. The drawback with UV is that it will also kill any beneficial organisms that pass through it. Ozone is a much better alternative and can quickly raise ORP levels in a system.
10. Refugium. Using a refugium is a great way to lower phosphates and nitrates in a system. Chaeto is usually the recommended choice although other species of macro algae are used just as effectively.

In freshwater planted aquariums, the use of a LED lighting system for aquatic plants will promote the healthy growth of plants, which will restrict the growth of algae. Light is one of the more perplexing components to algae control, as algae will thrive under low OR high intensities. Without aquatic plants, low light conditions will favor the growth of algae, since there is no competition for the light or other nutrients. Many actinic and metal halide lights will require replacement after 6 months. In most saltwater applications, the lighting intensity will be greater and if there are no competing organisms, algae has all the light it needs. However, sudden appearances in a well-established aquarium could be related to a decrease in metabolism in the competing organism caused by a decrease in intensity of older lights. Once again, replace the bulbs.

It can't really make any difference for the green algae, and all the other photosynthetic organisms have evolved to use sunlight, and photosynthesis has probably only evolved once. Because of the different photosynthetic pigments in diatoms, cyanobacteria and red algae they might use slightly different wavelengths of light, but you are still back to having all evolved in sunlight, the spectra of which is pretty constant. If I was to guess that any of these groups are preferentially favoured by different wavelengths of light, when compared to the Viridiplantae, my suggestion would be the Red Algae. If you find sub-tidal red algae in deep rock pools on the shore they are often bleached, presumably by the extra energy of the sunlight when it isn't attenuated by a reasonable depth of water. The freshwater pest red algae aren't red that makes me think that they have a lot of carotenoid pigments, that mask the photosynthetic pigments and give them some form of sun-cream.

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. 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. 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. AllPondSolutions Tropical and Cold Water PLED Lights work brilliantly as aquarium LED lights when you need to maximise photosynthesis and plant growth while ensuring efficiency – they come with an extendable bracket for customised placement.
