Anyone interested in about 5 big buckets of very dead base rock? This rock was last in a tank about 3 years ago, then sat out in the sun for a year before being stored dry in buckets. There are some large pieces and some smaller ones. Rock was used for seascaping a 210 gallon tank. I suggest soaking in tap water for a few weeks before use to leach out organics. Rock is currently in San Francisco near 19th and Holloway Ave. Ideally someone would pick up in the next few weeks. Please email Jonathon.stillman@gmail.com if you would like the base rock.
