I have 5 x Evils' PAR 38 20k LED bulbs over my 80 gallon 30x30x20h rimless cube. The bulbs have 40 degree optics and sit about 9 inches off the water. My water parameters are good. Nitrates are a little high (between 5 and 10), but otherwise everything else is right on the money. This is a complete BTA tank and my BTA's seem to be losing color with these bulbs. I know they put out the PAR numbers, but I'm feeling that they don't have the color spectrum for BTA's. I've only been using them for a few weeks, but I've seen a noticable color loss. Do you think they were a complete waste of $500? Anyone else finding good results with these bulbs and anemone's? Any suggestions/help/advice would be much appreciated.
