Okay so my tank has been running for about 2 months now. I have 2 clowns, diamond goby, and a cleaner shrimp. Been checking parameters 2x a week just to make sure I got the testing down pat for all the test, I use salifert test for now. Im starting to get a rusty colored looking algae covering my rocks. Its not bad but I wanted some input if anyone could tell what exactly it is from the pictures. Do I just let it run its course or is it something I need to personally take care of. The second picture you can tell how white the rocks were cause the sand bed was there and then my goby moved all the sand around it, you can tell the difference in the color of the rock there.
