I shut down my reef tank 4 years ago and I'm starting up again. I saved my rocks so I have about 100 lbs of rock that has been sitting in a tub in my garage for those 4 years.
What do I need to do to prepare it for use again in my new 90 g tank, which I am in the process of filling with water (that slow drip of the R/O!).
For the moment, I've put the rocks in a 20 gal brute in my basement with saltwater, a heater and a pump for flow. They've been in there for 12 hours now so I know I'm at t he beginning of the process.
Recommendations for next steps? Thanks.
