Am I looking at GHA or Bryopsis?

[DK Oceanics]

LSF told me this could be bryopsis. I’ve been reef keeping for over 10 years and lucky have never ran into a GHA or bryopsis problem. So this tank has officially been my first problem tank!

This tank has been set up for 5 months now.

P04- 0.02
N03- 2-5 ppm
Everything else is in range.

Running Rowaphos and carbon. As well as a protein skimmer.

I have tried a reef flux dose which killed all my livestock within 3 hours. So any other suggestions are appreciated. I have been doing weekly water changes and siphoning out the algae, it is now at a super short turf like length.

Quite sure that’s a GHA. Imo

Did you purchase the Reef Flux off Amazon? If so, you likely didn’t get the real deal. Better to get FluxRx from a reefing supplier or LFS.

It’s GHA, Bryopsis has more of a feathery look.
