I have lost the battle......

Muriatic acid but you will KILL everything on there, and I mean everything!
Fill trash can with water and mix in there about 10 to 15% of the gallon MA, have a pump running for 24hrs.
Dry your rock three days in the sun and have it cured in the same trash can this time with fresh water and after a few days have salt added to it in order to run a skimmer to get most of the phosphate out.
Replace all plumbing from your tank and clean all equipment with MA too.
It will take some time but mean while you can have your corals in a frag tank with a small fox face as he will clean your corals

That is the bad one. The large singular round Valonia are bad enough. The small pear shaped species have very invasive roots into the rock and tend to go sexual far more frequently. Ending up like well what you just showed us.

I've had ups and downs also. I like to look at natural ways to solve problems...one of which is to kill the stuff off yourself. When I finally gave in to the idea that astrea stars ate zoas, I had thousands of them in my tank. Every time I walked by, I would pluck few out...until it got to where I rarely saw one. When I got hair algea, I pulled the rocks out, scrubbed them with a wire brush to remove all I could, and let them dry out, to kill the rest. When I had aiptasia take over, and I mean the little ones that are hard to get because they pull into rocks so quick, I used vinegar to kill them. I also got a copperband butteerfly, and soon as he ate all the little tubeworms, he had them wiped out in a week. Bubble algae vs a determined ME? haha!!! Bring it!!

foxface fixed my bubble alage issue.

Soooo I actually had bubble almost that bad, no, seriously! It was over growing many of my coral. I bought 6 emerald crabs, it took about two months, and then I realized, holy cow, the crabs are working. Now, one emerald crab maintains my tank. I still have bubble algae but only in the overflow. I've been to the point where I want to torch it all and start over, but there are other ways!

Here is what I am dealing with.

Every rock is completely covered. It will be impossible to get it all.

Dude that's intense! [emoji15]

My simple answer is throw the rock away Place any corals you want to keep in a QT and remove them from their frag plugs and watch them for 6 months in QT. Completely sterilize the whole tank and all equipment.
