Curing old rock

[Slacker300z]

Hello fellow reefers!

I have about 150-200 pounds of old rock from my build 10ish years ago. Probably longer at this point. Whats the best way to start curing it?

Depends on the how it was put away/stored really and whats potentially in/on it..
If just thrown into a container and stored then giving it a good wash/scrub or powerwash wouldn't hurt to remove any old/dried organic material (algae,poop,etc...)
Then cure like any other rock..

Some may choose Bleach or Muriatic acid treatment to really make it "new again"..
Others may just throw it right into saltwater and start the cycling process.

Do you think its clean and more importantly phosphate free/low? If so cycle and be done..
If not curing/acid/bleach,etc... may be beneficial..

Really depends on specifics of that rock and its state of "clean"..


I had rock stored for 5 years or so and just took it out to the driveway and hit it with the powerwasher then into the tank to start the cycle it went..

It was just taken from my taken and stored in bins. Power washing is a great idea. Living in CT its not ideal now. Might have to try the other options. Thanks for the tips!

A good scrub brush/rinse in the utility sink/tub will in essence to the same/similar and not require you go into the freezing tundra..

Personally, I'd grab a large trashcan (or several if you need them) mix up some saltwater and throw the rocks in there for a couple weeks. Put a heater and a powerhead in there, maybe a couple pieces of cured rock..
