unfortunately i cant send a pic because i have nothing to take a pic with!
Anyways,.. there is a white powder that appears sporadically amongst my reef tank. Every once in a while there will be a little pile of it by morning. I would think if it was some sort of fish secretion it would'nt be white. Almost looks like some little critter (the size of a hermit crab or something) lost his dinner in a small 1" radius. If anyone has seen the sporadic small powderings, please let me know all is well. Thank you. Ill get a pic ASAP if no one knows from my rambling.
