Can someone ID this macro algae for me???

[Kevro]

It's beginning to grow more than I'd like it to. It's covering my rock. My Blue Hippo Tang doesn't seem interested in it either.

Another problem with it is that is grows really close to the rock and is difficult to get it all off. Everything has a "sloppy" look to it when this a;gae is on it.

Any advice????

Dictyota sp. They are good nutrient eaters,but they are known to grow quickly and become a pest if not trimmed.
