The red in the secondary filter is because I started the MH after changing the primary and I use Automatic Transmission Fluid to prime the filters. There is still black in both filters.
After that I made a coffee and headed over to the courtyard just in time to see John cleaning his composting toilet. Everyone swears by them and I agree they have their place, but I can't quite see me wiping poo out of the toilet as a regular maintenance item. The boys will have to do a lot of convincing to get me on board. They must be good because there are at least 7 rigs here that use them. And just a plug for Brian Boone cause he sells them on his web site and of all the people who need one, he is the king!!
John gave a little demo on how to clean up poo from a composter. The brown you see is peat moss not poo by the way. But what is on his rag is poo I think.
