Curing Rocks With 15% Sodium hypochlorite

[deividas]

As title says, the only "bleach" i can get my hands on, that has no additives, to cure old rocks is 15% Sodium hypochlorite, would this be ok to use on the rocks? or will this be too much? "Sodium hypochlorite 15%, 180g/l, L" this is the solution i would be buying.
a link to it is here but its in Lithuanian so i doubt it will be of any help https://lerochem.eu/pagrindinis/48-167-natrio-hipochloritas-180g-l-l.html#/27-dydis_talpa-5_l

there is also a spec sheet of what's in it;

Why are you doing this? What type of rocks?

You can use vinegar instead of bleach if that’s easier to find.

does vinegar remove the phosphates from the rock as well ?

I’m not sure. I used vinegar to get rid of the old dried algae and organics that were in my used rock. I wasn’t trying to do anything else.

@Randy Holmes-Farley any input?

Bleach will remove organic matter, but not inorganic phosphate.

Acids will help remove phosphate and dissolve the surface of the rock, but not necessarily remove organic matter.

i Bought old Rocks from a local reefer and it has all sorts of dead organics on the rocks, so what i was thinking, putting those rocks in the Sodium hypochlorite + water solution for a week and then, curing them again for a couple of weeks, just to be on the safe side.

i would be mostly trying to get rid of dead organics, and the phosphates i would just cure them again for a month or so to get those phosphates out

will this Sodium hypochlorite which is at 15% will be ok to use on the rocks? will it not be too strong/not dissolve my rocks and etc.? because from a little digging i see that most people use Bleach which has the Sodium hypochlorite at 6-8 %

Calcium carbonate will not dissolve in any concentration of bleach.

I used bleach and muriatic acid (separately with Seachem Safe and Sodium bicarbonate as neutralizer for each).
Soaked in bleach several days and acid for few mins only. Use in open air area following safety precautions. BRS has a video where they tested bleach, acid or both. I used it because I didn’t want risk of any pests in my 650 gallon tank. Kinda hard to lift out 40-60lb pieces to remove pests after. Also had bad experience with cirolanid isopods in previous setup as I was using fresh Caribbean Sea live rock.
