Here are two pictures of my sandbed. As you can see, there is a brown substance growing on the sandbed. At first, I just thought it was die-off and other stuff falling to the surface, but I cleaned/stirred the sandbed yesterday which cleared it up, but it was back today.
There also looks to be very small bubbles on top of it. You can't see them in the pics.
Any idea what this is? And how can I get rid of it?
My Nitrates are running about 10 ppm.
I have a number of snails, crabs and a Yellow Tang to help with algae.
Thanks,
Paul
