I have a maroon colored algae spreading on my live rock. It is similar in color to cyano, but it is probably 1/4" thick and more white colored underneath. It is velvety to the touch and very difficult to remove. It won't come off with a turkey baster and I can not siphon it out. I can get some of it out with a toothbrush, but I can't reach in the nooks and crevices and it grows back rather quickly.

The tank is a 65 gallon reef with a 1" sand bed and 75lbs. of live rock.
It has a finger leather, a frogspawn, some button polyps, and 6 fish. Nitrates are less than 5 and phosphates are .02.

Thanks in advance for the help!
