I started soaking two pieces of spiderwood last Tuesday night in a very large Sterilite container. After only about 4 days, the smaller piece had sunk. The larger piece is still floating (and is currently being held down by 2 chunks of granite). I'm changing the water in the tub every few days. The wood is releasing a lot of tannins, the larger piece of wood has some pretty slimy patches, and it smells a bit putrid. From what I've read, all of this is to be expected. What I'm worried about is the fact that the big piece of wood has multiple areas where the wood is getting pretty soft to the point that I could scratch it away with my fingernail. I'm also concerned about the fact that some areas of the wood have gotten WAY darker. Could my spiderwood be rotting significantly already? The smaller piece of wood doesn't have any of these raspy bits or splits. Also, there are a couple of pretty large cavities in the wood. I can feel that the wood is pretty soft inside of there. I'm a bit worried about what might be going on in there (maybe I need to get a bottle brush to clean it out?) and also about a fish possibly getting stuck inside. I've attached a lot of photos to help you see what I'm talking about. I've also included a photo of what the wood looked like when I first began soaking it. Many thanks! If this wood seems wonky, I'll let it dry out and return to it someday in the future.
