anyone with sundial snails?

Despite how unfortunate your situation is, I must say that you have an impressive amount of mojanos. If you could find someone that has a fish that eats them, they'd probably be glad to help you out by taking that rock off your hands or potentially doing a pound for pound trade of your mojano covered rock for clean live rock.

I don't think any fish eat mojanos with any consistency.

They are also very hardy and will take a long time without light to die. Better bet is to cook the rock by leaving it outside for a month or 2

I would just pull the rock and cook it. Remove all the manjos which are left in the tank before adding the rock back in. Even if one is left it WILL multiply. Make sure you kill the ones which are in your sump as well.

Let the rock sit in the sun for a few days, then let it soak in mutaric acid for a few days. Rinse off as much crud as possible and let it soak in fresh rodi water for a few days.

If this is too much work there a few butterflys which will eat this stuff but its not guaranteed.

Good luck!

Using muratic acid on live rock can have a bad ending for the live rock depending on the strenght of the acid.
Muratic acid will disolve the rock before it does much damage to the majanos.
I have tried this so it's not a guess.
I placed a really nice large piece of live rock in a strong muratic acid bath that was loaded with majanos.
The next day most of the live rock had been eaten up by the acid, but there was still parts of the majanos left in the bucket.

Bleach kills, muriatic acid may or may not. It's basically super low pH, so like putting your entire rock in a super sized super low pH calcium reactor for a while It literally rips a layer off the rock via dissolving. Most of the time a few minutes is sufficient if the concentration is correct. Leaving it for an extended period is of little use.

You want to KILL, then it's bleach. You want to rip phosphate, copper, etc off the top layer of rock, then it's muriatic acid.
