How you know when rock is cured?

[JLAudio]

Ive been curing some previously live rock in a bucket with flow for 2 weeks now with bi weekly water changes, I havent changed the water in this last week and tested today and ammonia is zero aswell nitrite. Does this mean it is safe to put in main tank or should I wait the usual 4 weeks, which would be 2 additional weeks?

pick up rock and smell it, or you can add in the rock little by little (slowly over time) into the display tank. That way it wouldn't affect the tank.

J, I cured dead rock in a few weeks in a bin with just a power head and heater. The way I knew it was ready was when all test bottomed out at 0 except for the trate. I moved them into my display with the trate reading something like .5. Hope that helps..

Hi,
I always used my nose. it should have no foul odor.

I think the rock I gave you should be fine. I would wait about another half a week on the safe side.

yea im pretty sure its good but may wait if i have the patience which I usually dont

4 weeks is just a rule of thumb. all advice above r solid.

if amonia tests 0, theres no foul odor, water is not yellow or some weird other color and nitrate / nitrite are in your preference / range, its ready to use.
