I got a tank that i just started and began making it saltwater. I got live sand in it so far and using the stupid little hang on filter to circulate the water until i build or find a filter that will work cramped for space under cabinet. (Any ideas let me know!)
I am noticing black spots in the sand what are these and should i be very concerned.
Thanks
Michael
