HCA: Hermit Crab Association

I am pretty positive my crab has the mites that are harmful. They are not around it's food and I only find them when they come out of its shell after being submerged in water. I have been trying to get rid of them for months. When going online it says to submerge the crab in water and they'll wash out. I do this but they never seem to end. He's been in an iso tank for 2 months, no sand, just paper towels and regular crab stuff like food, salt water bowl, fresh water bowl, and a place to hide. I clean regularly but I still can't get rid of them. I think it's the shell, which is very cone shape and I'm not sure it's filling up to wash them out. The crab won't change shells so I'm not sure. Please help I do know what to do at this point.

Are you able to post a photo showing the mites?

This one came out of the crab's shell today when I was soaking it... again. https://photos.app.goo.gl/yJB1EnsaAhwewCM39 ... I'm not sure I got the photo to work. It's small and white and looks like a mini tick.

Are you seeing them on weak spots such as the eyes, joints, and mouthparts? If they’re parasitic that’s where they’ll be.

Are the mites also in the tank substrate and food?

Not a mite, this has a head and six legs so it's an insect. Likely booklice or springtail, they'll hang out on and in crab shells. I've had them before, they aren't harmful!
