Terrible Advice Tuesdays: Light Emitting Diodes (LEDs) won’t grow corals.
The rest of the story: I can’t believe I’m still hearing this idea passed around especially considering mounting evidence of LEDs successfully growing coral. From a scientific standpoint, here’s one experiment that showed that LEDs are a viable choice for growing corals – even in aquaculture facilities where fast growth growth is the goal.
From a user perspective, I’ve got several clients and countless followers growing corals (even hard corals) under several different name-brand and D.I.Y. LED fixtures. Since 2011, I’ve had only LED fixtures over my tanks with good results.
Of course, any topic, if you go looking hard enough for the evidence you are after – in this case corals not growing under LEDs- you’ll find it. Remember that the outliers on a bell curve are just that – outliers. They should not be used to make a decision where there is plenty of contradictory data.
Are LEDs still a relatively new lighting type for saltwater tank? Absolutely. There is still lots to learn about LEDs and their application in saltwater tanks. (For you Virtual Tank Build Program participants, one whole session of the program will be spent discussing LEDs as well as other viable types of lighting)
LEDs are a suitable option for lighting your saltwater tank and the future is only looking brighter for them. Don’t let the few people who have had bad experiences cloud your vision.
