Bryopsis or Turf Algae - what am I fighting?

[squarereefer]

I am seeing my first algae out break in this 7 month old tank. I thought it was GHA, but it's unlke any GHA that i've ever had in previous tanks. It's basically glued to the rocks and does not pull of and almost impossible to scrub off. Nurtients are always low with phos generally < .05 and nitrate < 1. I've been trying to raise nutrients slightly with NeoNitro and feeding reef roids but admit that I get off schedule and end up low again.

I can't tell if this is as "fern like" as other Byropsis photos.

Looks like bryopsis. To test, pull it. If there is a tug or a rip like you are ripping gras out of the ground, its bryopsis.

Flux RX would be my recommended treatment for bryopsis.

The strands will look like a fern leaf if it is bryopsis.

That's why I posted - it's defintiely not GHA. I've battled enough GHA in other tanks to know what it looks and feels like when pulling from rocks. But at the same time, I am hesitant to say it looks like a fern. It does have multiple strands off a single stalk (for lack of better term) but it doesn't look exactly like some of the classic fern bryposis photos i've seen posted here.

I am a little worried to start a reeflux treatment without knowing for sure what I am chasing.

On the sand bed, it pulls easily in large clumps like GHA. However, on the rocks, it's attached firmly and very hard to pull off. It's even hard to remove when scrubbing with a toothbruh. I am researching all the past threads about Reeflux now and will likely try it. I am just hesitant since it does not look as fern-like as other photos.

I would go with flux rx over reef flux. I think the dosage is better.
