GHA or Turf Algae or ???

[Saluki2003]

Can I get some help identifying this algae? It’s only showing up on my rocks. There are some thicker spots and a few tufts popping up in other areas.

Bryopsis? Flux Rx works like magic. Gone in 14 days. Poof!

Not Bryopsis but a similar algae known as derbesia and mixed with hair algae.
This is one of the more challenging of algae due to need of its complete removal. Removal is best accomplished by taking the rock out of tank and placing in a container of tank water. Then you will want to pull as much as you can by hand and discard. With a dental pick or small crochet needle, pull the roots off the rock. YOU MUST GET EVERY ROOT OR IT WILL SIMPLY RETURN !!
After you are done return rock to tank and reduce white light intensity and even hours of white light and add the following cleaners which will help with control. These guys will consume bryopsis but not as fast as bryopsis can grow - They will never keep up.
Pin cushion urchin, Chiton snails, pitho crabs, and larger astrea snails

This procedure is not as bad or time consuming as it seems. Assure phosphate levels do not become elevated which helps feed this algae

If you'd like to be a beta tester, I would send you a free sample of Flux Rx and Im gonna say it will work on this algae......as it does with bryopsis and gha......this could be in the same family. Doesn't hurt to try and could be a painless solution. PM me and I'll send ya a free sample enough for your tank.

Thanks Vetteguy for the proper id.
