Hi GW, I'm thinking that it might be time to close down the BSF for the year. It's cold in the mornings, and there are not many new BSFL. I have a lot of "stuff" in the bottom of the BioPod that contains 1000s of BSFL in various stages. If I dump it on a big black plastic sheet on the dock, I think the heat will force most of them to crawl away and fall into the water. The fish will love it, and I should be left with some good soil for next year. Does this make since? I will do nothing until I hear from the MAN (you)!
