Clean, used substrate is available for pick up in Annapolis, MD. All substrates are from the CaribSea Super Naturals series. There is Sunset Gold sand, Peace River fine gravel, and Gemstone creek medium gravel perhaps mixed with some Jelly Beans. All must go by May 1. After that, it goes to the rubble pile at the county dump.
Forgot to mention earlier that I also have a fair amount of river rocks, some quite large in the 180g. Mostly various forms of granite.
Need to bring own bucket?
