Salt Deposits

[Rred]

If you are not sure of your local tap water, or it is well water, you can often get a free water test from a local "county extension" or other office. Or for $15 get a dissolved solids test pen online, they just dip in the water and display a reading of the dissolved solids content.

If you are "rinsing" by soaking? I would do 3-4 water changes, at a minimum, because just one soak just makes that batch of water salty, it isn't the same thing as rinsing in running water, or multiple water changes.

Yeah, I suspect you are right about not changing the water enough.

Yep, it was around the face plate where it screws into the body.

Diving in salt water this is unavoidable, I rinse my regs straight after a dive, take home, hose off and then soak. I still get salt deposits where the face plate screws onto the case. The only way to clean properly is to remove the face plate so you can get at the threads.

I usually just lick it off, if I can't see it, it isn't there...
