red hair algae difficult to remove

[Fishbike13]

like the title says, need some help identifying this algae. It is only growing on a few rocks, nothing on the sand, is hairy, and doesnt change between night/day. Same red color under all white light. Takes a bit of effort with tooth brush to get it off the rocks.

Params are

Nitrate-5ppm (nyos)
Phosphate- .06ppm (hanna)

Have carbon and GFO in media bags sitting in the filter sock. System volume is about 30 gallons (20 long display, 20 long sump)

I have UV, chemiclean, fluconasol, and dino x at my disposal, but not sure how to attack it.

Any help is appreciated TIA.

Remove the rocks and the poor some hydrogen peroxide over the algae. Scrubing the rocks in the tank will just spread it. If you scrub them rinse with hydrogen peroxide after to kill the loose bits of algae.
