While disinfecting all of my tat structures (coco hut, vines and aquarium decor) of mites yesterday, I just dumped everything that needed to be cleaned in a 3.5 gallon bucket of MSW. This included all seashells which was the first thing I put in (so bottom of bucket). Out of force of habit for disinfecting, I put in like a tablespoon of distilled white vinegar and didn't think about it until this morning while rinsing everything off.

All seashells for hermies are faded white. Nothing cracked but just a kind of dull white or half white and half still with color. Is that ok or do I need to chuck these???

I have another bag of seashells ready to use for the guys which I put in last night anyways but I just wasn't sure what to do about this. Advice?
