Diy rock

[mcbdz]

I have a question for anyone that has made rock. How long does it take to cure/dry a rock? Around 20lb large ones. Thanks

Just needs to dry. Then rinse it

Just got some from online and washed it and drilled some wholes for plugs and it was like muddy clay. Worried it wasn't cured wnough.

I just got done curing some rock...or so I thought. Question for anyone who knows...
I made probably close to 50 lbs using portland cement, soft water rock salt and crushed oyster shells. I let it cure in water for over 2 months and just added more than half of it to my 180 gallon. It's been in the tank for roughly two weeks and it has not caused any changes to the salinity, PH or Alk. I just decided to break up some of the bigger rocks that were still in the curing bin and noticed there was still rock salt in the interior of the rock. I tasted it and it was salty. Will this slowly cause issues with the current rock in my tank?

I made my own background out of cement product and I cured it for several months. I'm not sure what the bare minimum time you can cure it for, but fresh made portland cement defiantly takes longer than a rinse.
