Cleaning LR

So I come home for the weekend from college and my mom says she has a surprise for me. It turns out her coworker is tearing down is 55gal tank and turning it freshwater, so sad. Anyways, he gave me all of his live rock, ;D. The only downside is he tank was not the greatest and there was aptasia everywhere. So I need to clean this rock somehow, preferably just kill everything and turn it back into base rock. What do you guys think will be the best way and quickest way to cure this rock?

 

only kill the rock that has bad things on them. if there'a a few really good ones that have coraline and dont smell or look like these bad hitchhikers then I would keep those rocks as is.. thats my opinion but your still taking a chance.

 

1. Soak the rock in a 50/50 bleach and water solution for about 2 days.
2. Drain the soaking container then soak the rock in clean fresh water for 2 days.
3. Drain the container again, rinse the rock in fresh water and soak again it in fresh water again for another 2 days.
4. Then add a 2lb box of baking soda per 15 gallons of water and soak the rock again for 3-4 days.
5. Drain the container then soak again in fresh water for a day then remove the rock and let it sit and dry for 3-4 days (The baking soda soak is to neturalize the acid and low P.H from the bleach).

I read it somewhere and copied it down. Credits to the OP.

 

It all had bad stuff on it. He had the worst aptasia outbreak i've ever seen plus some disease or something that killed every fish or invert he tried to put in there so i'd rather just play it safe and get rid of everything.

 

+1 on this method, don't put someone else's problems in your tank.

 

Precisely why i want this rock turned back to base rock.

 

If you have a big spaghetti type pot just boil the rocks and then soak with RO water overnight and you'll be fine by the next day. Then go to the LFS and find a nice piece or two of cured live rock and quickly rinse with RO water to chase out any hitchhikers and add to the tank when it's filtration is up and running and this should speed up the process. I always quickly rinse live rocks after having an undesirable hitchhiker (mantis shrimp) that is still in my tank.
