So I finally gained the courage to split my original Mother SCOBY from a few of her babies. I then made qty 2 new batches - one using the mother and one using the "baby" SCOBY (I kept the babies together, maybe 2-3 layers). Now, the mother stayed on surface like I'm accustomed to seeing. However, the "baby" SCOBY sank straight to the bottom. From reading the FAQ and troubleshooting guide, all seems to be ok with this happening. However, a few ?: Can I reuse a "sinker" or should I discard it once desired fermentation is complete? I assume a fresh SCOBY will form at the surface despite the original SCOBY submerged at bottom? Once "sinker", always a "sinker"? I mean, if I can reuse it, what are chances of the SCOBY regaining its buoyancy at some point? Thanks in advance for the feedback!
