Update:
Toadstool mushroom slumped over on Friday night, but then it started shedding its clear, top layer (including the red algae looking stuff) and most of its little extensions have come out. I'm worried because it is slumped over, but hopeful with the tiny polyp-like extensions out. Is the leather likely to recover after slumping over? I can send pictures later if that will help.

My alkalinity is going down slowly because I'm not adding any more supplements -- even during top-off. The dKH has dropped a couple of points since last week -- down from 12 to 10. At some point, I'll have to resume supplements (right?), so it appears I'll need to adjust the dosing amount.

Any new suggestions or recommendations for my leather?
Thanks again!
