You will need to have to put the 40 degee optics pretty high above the water level. Be careful with sps b/c you can fry them. Believe me I have.
I run 2 spots at both 60 degrees. 1) 19" from the sandbed + 7" from the waterline. 2) 16" from the bed + 4" from the waterline.
I was going to see if I can borrow someones PAR meter to figure out placement. I could just bring the bulbs to a meeting or whatever.
I'll probably have to put mine 12" (at least) above the tank. Sandbed is ~9" down and the top of the rocks are about 4" down or so (tiny tiny tiny). If its too strong I can always just swap to using one of the two bulbs, we'll see. I'm really excited about these LED's though. :inlove:
I just did a 1.5gall water change and I will check the nitrates once it settles down, but I think it should be good now that I stopped using the bad RO water.
