Red algae

[thanhjenn]

I have this red algae problem and I'm not sure what it is. I know it is not red slime. It seems to be in area of high flow. It is not thick like green hairy algae. It forms almost like a thin fuss layer on the rock. On one coral it grew where the dead tissue is and it seems to have roots spreading (1/5 mm in diameter) to the live tissue. I tried taking pictures but does not seem to work well. The spreading of these algae are almost like veins on the leaves. Do you have any idea what these are?

Thanks

sorry about the poor quality pics
