So I think I have reached the limits of my local forum help. I've tried all the suggestions and at this point I feel like giving up. I hope you guys can help.
To begin my tank is 20g and has been up for over a year.
On 9/03/14 I saw this appear on my rock.

So to begin, I started doing weekly water changes to lower phosphates. I also got much better phosphate media and got a phosphate reactor. I got all my numbers in shape. Nothing got better.
So on 9-13-14 the tank looked like this.

So I moved onto the next suggestion add hermit crabs to gobble it up, which I did. Here it is on 10/10/14

Still no changes. So starting on 11/01/14 I also raised my magnesium with kent tech M to 1400-1500, and have kept it there. Here is the tank today 11/11/14

Please help! I really don't want to quit this hobby after 10 years.
