So we know that LED’s can put out the intensity reefers are looking for, we’ve seen the spectral graphs and even the convincing side by side comparison. Nevertheless, there is something exciting and extremely gratifying about having solid evidence of what an LED light can do to grow corals over a decent length of time. A big thanks goes out to Stephen Pollock, owner of AquariumLED.com, for not only sharing this video with Reef Builders, but also for doing the hobby a favor by setting the bar in terms of what an LED light can do for the coral aquarium. This video is exactly the kind of fodder the hobby needs to get excited about LED lighting. Not only are the corals in the video growing, they seem to do so at a reasonable pace and with fantastic color. We can’t believe that there are no actinic supplements being used with the ALED and the SPS corals look fantastic. Sure the setup overall appears a bit experimental but we’ll be testing one of these on a mature 29 gallon uber-mixed reef and we’ll let you know how far 42 watts of led light can go.

Id just stand back and watch for a while on this one. They had that same light over a 12″ deep tank at MACNA and par on the bottom of the tank was only 200. I was not impressed. In the video I see the light is close to the water and all the corals looked like they have been recently placed. I really didnt think the growth was all that great. I hate to be a pessimist. Id really like to see the same tank in a year. Thanks for the vid!!!
There’s been some debate about the applicability of PAR readings to LEDs but I didn’t quite follow the science on first read.
Certainly LEDs are expensive for what they are, but the price will keep coming down for sure.
I’m thinking of trying 6 AquaRay bars (the main LED unit here in the UK) on a new 80 gallon soft coral and LPS tank. That’d be just 70watss of power over a 1m x 60cm x 60cm tank. If it works, I’d be prepared to pay just to feel better about my carbon footprint!
