Mysterious crystal formation in underwater housing

[spoolin01]

Yeah, wish I had noticed. It couldn't be seen looking through them in the case in normal light, only against a white paper background. It's pretty faint...

You can use other types of silica gel bags, like these for example: https://www.amazon.com/Rechargeable...coding=UTF8&psc=1&refRID=EE4RSD4A54A3S47TSDWK or other sizes.

These do not have the blue indicator, so just replace the bag every time you open the case.

In many cases the soft form of those packets might work better, and they are about 1/10 the price of Moisture Munchers.

You have a leak and a future flood.

?? It now appears the crystals were spilled dessicant, not signs of water intrusion.

The desiccant itself is not (very) toxic, but the color indicator that is most commonly used, is.

 

[spoolin01]

What is the indicator?

 

[archer1960]

The common blue/pink one is cobalt chloride.

Not that it is a serious concern, but the amount present in a couple of crystals should be far from a problem.

Yup.
