I have a 150w 14K Pheonix HQI bulb over a tank with a height of 12". Pendant hangs about 6" from waters surface. Do I have enought light to keep crocea clams? I currently have two maxima clams that are doing fine. I have them in the sand, but I would put the crocea higher up on the rock work.
 
i am wonering the same thing for my tank, is this sufficient lighting for a tank to keep croceas and maximas?
Thanks
