Firing up a setup for the first time in 3 years.
Howdy folks! It's great to be back.
I have a roughly 40 gallon tank setup here that was running 3 years ago, then we bought a house that didn't have an appropriate spot available so it sat in the basement for 3 years. The sand stayed in the tank and dried up. I also found a bin with some live rock that is now... dead.
What do I need to do to this sand and rock to be able to use it again?
The rock has greenish stuff where coraline used to be.
Thanks for any advice!
Jeff
