Aquarium Advice Addict
I just wanted to share that my 300 gallon reef is now illuminated by white and blue LED's. Over 300 of them all of them each at 1 watt output. Replaced about 1200 watts of metal halide. Practically no heat, the light quality has set the corals off and running. I wish I had done this earlier, but these high output LED's were too expensive. I had a guy on the west coast build the panels, they did not come from the aquarium trade, but they work perfectly. Highly recommended as my chiller hardly ever kicks on now and I am saving loads of power.
