It looks brown on my plants. I will get a pic later. I have Anubius, hornwort, and some waxy plant that it has pretty much killed. I have 2 crappy fixtures on top of my tank (56 gallon column). The tank is 2 feet tall. One is a 40 watt perfecto and the other has two of those curly bulbs. They are pretty old (50 watt). Lights on from 12-3 and again from 6-10. Also, I have been using flourish after weekly pwc.
