Aquarium Advice Regular
Hi- my tank is a couple weeks old now and i am starting to see some good growth in the sand and on the live rocks. However, I am still not 100% positive at what I am looking at. Over the last day, the brown growth has become heavier on the rock. I attached a pic of the front of the rock (which has gotten much darker) and the back of the rock which is more the color it started out as. I also attached a pic of the growth on the sand. Is this all normal?
