Of molters, mold, and more unnecessary panic

I had mold acouple weeks ago in my crabitat.
So i had to bathe my crabs in salt water, then fresh water.
Well, as I was digging all my crabs up (which is stupid to do unless you absolutley have to, like when you have mold, or worse, mites), and I came a across Legolas. He looked like he was torn up, and I started crying, not thinking that he could've been molting (DUH). Since he molted in march, i didn't think it was possible for him to need to molt again. Well, that's what happened, the bugger molted on me again.
Grunt FINALLY molted last week, but she hasn't come up yet. I looked on the bottom of the iso cage last night and saw no signs of her exo, so I'm expecting her to come up any day now.
My hydrometer broke, so I have to get a new one. Hopefully i'll get one that can be calibrated.
