They are all nocturnal.  And since it has nearly an 18Ē reach,  it doesnít have to come out.

Started treatment today....about 6 hours in, and some of the hydroids are fully retracted, most are partially retracted.

So far the tube anemone seems to be okay.....it was rooted under my base rock, and wasn't going to move.

Dosage was approximately 2 mg/gallon.   ( https://www.amazon.com/gp/product/B009TAQ4OI )

At 14 hrs, all of the hydroids are retracted.

At 48 hours:
    The tube nem started to look not so good, but it released itself from it's tube, so I was able to get it out of the tank, hopefully it will recover.

    The hydroids have been mostly retracted this whole time but the are still sticking out the of the tubes a little bit.

At 72 hours:
    Not much change.   So I re dosed the product.

Well after 2 x 72 hour treatments, while they are retracted, most are still there, and will probably live.

I guess I'm left with manual removal or replacing all of the rock in the tank.    :angryfire

Would a 3x-4x concentrates dose be effective? Is it expensive or anything in tank you worry about?

Perhaps, itís not terribly expensive.  Everything im worried about is in my frag tank, which I isolate during treatment.  Going to do a water change and carbon.....see what really survived.  Then hit them again.

Could you bleach the rock?  I have done it to remove nuisance zoas/Xenia. BRS has some good steps. I like it better than acid.  Used fresh water bleach, fresh water rinse, salt water rinse both with prime. Iíve got test strips and brutes if you want to try it.

I think 🤔 I did about 4 weeks , but 2 weeks might do it. Crystal clear rock now.

Sure I could but since it is on every rock, I'd have to empty the tank to nuke it.

For the record, I found nothing that worked....it is back in full force.  Nice green wavy carpet on the rocks.  Time to replace the rock....

I have a few of these same hydroids. After reading this thread, I decided to take care of them before they get out of hand. I used epoxy to cover the majority of the patch and a laser to zap the ones the epoxy missed. After a couple days, the ones I have lasered are still gone. Thought I would share if this would be helpful to anyone.

Iíd like to know what fuels it. Iíve had a couple little patches of it but nothing I got concerned about and it hasnít really spread. But Paul sounds like his is the opposite.
