I recently had to put my Coralife 5500K MH bulb back into my pendant when my new Xanium H2 bulb became very dull. The increased light caused what people call Diatoms (I just call it brown algae) to start up on my DSB. I noticed today that my Sally Lightfoot was industiously working on the gravel, and eating the brown stuff. He also eats all the Bubble Algae, so he is a useful critter to have around. :D
