Whoops. Forgot to put the radiums in there too.

I have read Dana's article and now this one. Seems that there needs to be some studies done where it is decided what exactly we as reef keepers can properly supply our corals and to what level is to omuch or too little.

With Dana when you get up to 400W you are going too much. But only with PAM if I remember right. But with Steve 400's are concidered strong lighting and 250's are moderate. Only 1000's are intense.

oh well glad I don't sit and study this stuff for a career.

I have thought about putting different temp MH's over this tank. Was thinking about two 175W on either side of the 250W in the middle. Ditch the VHO's and just have two actinics that come on for sun up sundown and shut off once the 175's kick in. After reading this I may to exactly that. As long as I can find a 175 bulb that is a blue spectrum. I am going to look into the 14KK's now. See where they spike. If it helps with growth and proper light specturm being given to the corals it's worth it IMO.

If I had a large enough tank I'd do the track lighting and have it run the length over the course of the day. No doubt in my mind. Not only would you not get areas of different colors that are constant, but you'd get the higher intensity light hitting all areas of a coral head. like in nature when the sun moves. Just can't do it on a 24" tank. ;)

I think it would look cool having 600W of MH over my tank anyways. :eek: lol

I can't seem to find much info on those 14KK's as far as spectral analsis goes. hmm. the 10KK's at J&L are ushios. and not AB's.. hmmm Time to go digging. I know what to look for now. a big spike at 450nm. :D

Whatcha think Brad?
