Cooking rock necessary?

hammerfrog · 06/04/2011, 11:19 AM

I tore down my tank 2 months ago. I dried all my rock on my deck for 4 days and then packed it up in a rubbermaid container. There is 50 lbs of Marco rock, another 30 lbs of Fiji rock and about 40 lbs pukani rock that was in my aquarium for the four months that it was up and running.
I finished my move and now I am going to set up my 90 gallon aquarium in the next month or so.
I am doing a foam rock wall to cover the overflow with a bridge connected to an island.
The rest of the rock will be in the sump.
After reading over RC I see that some people use bleach and then acid to kill the organics and phosphate on and in the rock.
Should I be doing something like this before I introduce the rock back into my aquarium?
Thanks

I would scrub the rock with a nylon brush and rinse with ro water then let dry in the sun a few days to create base rock.

IMO, the answer depends on what sort of conditions it came out of, but it can be a good plan to strip the live rock. Before setup is the only chance you get. If it was a high phosphate condition, I'd use acid on it, and if there is any visible organic matter, I'd use bleach (before acid).

In any case, it is probably covered with dead organisms like coralline algae and others, that are best removed if you can.
