It's not the lighting. Are they active at night at all? Try to increase your pH to 8.0-8.4. Gotta separate them though so the betta will not be compromised.

If you have to check for heavy metals, have a water company conduct the test and send you the report. I'll enlist the help of my friend to see which one would be troublesome for the snails. I do know this though, with hard alkaline water, heavy metals tend to be less toxic. It's why I said to increase the pH a notch to see if it makes any difference.

I'm ready for the pressure.
The drama and the pleasure!
If there is one thing I want to see here, it's HUMOR.
I believe I can fly!
I believe I can touch the sky!
I think about it every night and day!
I stand in awe of my body.

When I checked on them today, I found two more dead (1 apple, 1 nerite). The others still smell ok, though a couple seem to have lost the ability to close their trapdoors. Of the 7 snails left, 5 have not moved at all in at least 4 days.

For testing with the water company, do you mean send them my aquarium water? Or are we talking about requesting a report of their supply?

I'm considering putting all the snails into quarantine. My reasoning is to get them into fresh water; away from any contaminants that may still be in the tank. Then I could also raise the PH without affecting anything else.

Request report about tap water. I'm baffled why your snails are dying while your fish is fine. How's the mussel yet?

It's not salty at all, is it? Snails don't like salt.

I'll look into the report. Mussel is still good.

Shouldn't be. I checked with a refractometer and it shows it as 0ppt or 1.00 salinity. Though its possible...

In the past I have fed the tank Azoo's jellyfish food. I thought it would be good for the mussel and didn't even realize it had salt. I just checked it: 22ppt! Water changes may have made it undetectable now, but it may have been too high before. Lesson learned: no more jelly food for the mussel!

However, I understand that nerite snails can easily tolerate salt as they switch between fresh and marine waters in the wild.

Lost two more today: 1 apple, 1 nerite. Three are still incapacitated (2 apple, 1 nerite), while two (nerites) are active. I'm starting to hope whatever it was is no longer an issue since two are active again. But I also fear it is too late for the three that are inactive.
