Scented bleach on live rock

[Dripdroppin]

I’m just going to make sure to keep most of my livestock I’m what will eventually be my QT tank and worst case scenario I will replace my 220 with a 180 because I have learned I am entirely too short for a 220 anyways lol

I don't know what the scents are made of but the "New Fresh Scent" bleach I used was not removed by a five foot PVC pipe filled with carbon after I slowly filtered the water through it three times.
It instantly killed my fish. Maybe lemon scent is something else.

Take my advice don't use the rock. It may not be contaminated and be just fine, but down the road if you have any problems (and you will being a new tank) you will always wonder if the rock is the problem. New rock is cheaper then livestock and WORTH the peace of mind.

Removes it from the water not the rock. So it has to be in the water first correct? That weans the whole time it is leaching from the rock it could kill stuff in the tank. How long will the rock leach this stuff?

Correct. Any material to be removed by carbon will have to leach from the rock into the water. Precisely how long this will take depends greatly on the compound, though if the compound has any solubility in water at all, it will eventually leach out.

Do you know the exact chemicals in the bleach he used? What was the scent used in that particular bleach? How sensitive are invertebrates to it?

No. Specific formulations are manufacturer-dependent. My comment was based on the common constituents of lemon-scented household items and the common detergents and emulsifiers that are put into household bleach formulations. But in the end, it isn't possible to know for certainty without an actual analysis of the specific product.

Are you positive it will be safe to use? Would you do it in your reef?

Carbon also removes copper from the water but you cant use rock that was in copper or even a aquarium.

If it were my tank, I wouldn't have bleached it in the first place, because while bleach is effective at oxidizing general organics, it's just not necessary if you're going to acid-wash the rock. And that's precisely what I would've done - I would've acid-washed the rock with 0.1N hydrochloric acid, followed by a thorough rinse, followed by a 2-3 week soak in RODI with changes every 2 or 3 days.
