You lose very little if any through the air. Gosh I wish I could find that article by sanjay joshi

 

Well then why do people suggest to raise LEDs when their coral is starting to bleach?

I'll try raising the lights and see if I have any adverse affects on my lower corals

 

They lose some but not as much as one would think, I don't think. Anyway, I would try raising them a bit more, especially with the optics.

 

You can, as long as you do not break the fixture in the process, you are good to go. They come right off, they are on holders with no glue.

 

You lose a decent amount of light at 16", but not enough to make a huge difference on shallow tanks. On deeper tanks, you can go lower and still hit the edges towards the bottom anyways.

 

I'm gonna keep my lights where they are and see how things go, I may decide to remove the optics in the future but for now I'll run with it and try to keep folks posted on how things turn out

 

whoops, just remeasured, Im 12 inches from the water line to the lights.

I have one of my new SPS in the mid of my tank just wanted to get it used to the LEDs before I move it up. Also most SPS corals well not most but a good amount them love thrive in the 300 to 400 par rating
