Bleach

you can bleach the rock i just did that this weekend to eliminate hair algae that came with it. now i know what store not to go to for liverock anyways please keep in mine that liverock is extremly porous and that bleach will soak right in. to insure you do not endanger your tank soak that bleached rock in a bucket of freshwater and change that water 100% twice daily or more. i got my 2 bleached rocks in a bucket with a powerhead running i have changed the water over 5 times and i still can smell a hint of bleach.....just keep that in mind anyone who uses chemicals to nuke there rock

 

I am currently doing the rock bleaching due to problem algeas also. from what I understand after soaking in a 50/50 bleach /freshwater solution is that you need just to rinse the rock in fresh water and then soak it for a few days in fresh water after this has been done it then needs to be soaked in saltwater as a reaction with the saltwater and the bleach occurs were the chemicals in the bleach become inert.
anyone who can elaborate on this? I would be keen to read any links on the processes

 

I would not put anything in my systems from another persons tank with out it being bleached or unless I know them and their tanks very well .
I would also never use L/R or sand .

My wife posted our method for soaking them and many here have applied our method with never a problem in doing so Its posted here somewhere Amcarrig posted it several yrs ago .

Tangster I remember reading about your method it was along time ago and I have yet to be able to locate the thread, If you or another can find it I think it would be great to add it to Jason McKenzie live rock Sticky thread , http://www.3reef.com/forums/live-rock/great-threads-about-lr-75674.html
maybee how to sterilize live rock

 

ok I think I have found a passage of info that should do the trick (it was added later that their should be added another day to each cycle
Soak the rock in a 50/50 bleach and water solution for about 2 days. Drain the soaking container then soak the rock in clean fresh water for 2 days. Drain the container again, rinse the rock in fresh water and soak again it in fresh water again for another 2 days. Then add a 2lb box of baking soda per 15 gallons of water and soak the rock again for 3-4 days. 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). "
