Can snails crash my calcium level?

I am not sure what is going on. My tank has no corals, no fish, only 7 snails. Three trochus, two turbo, and two nassarius. The capacity of my tank is 32 gallons, more likely has 28ish due to rocks and such. My calcium level is normally 390ish, and last night it tested at 60 - 70 ppm! I was a bit shocked and tested it 2 more times (Red Sea Calcium test kit) and the results were the same each time. It was a bit late so I couldn't run over to Neptune for a water test to make sure it really had crashed. All my other levels are pretty average, phosphates are up from .06 to .12 but I did feed the tank that morning.

So bad test kit? or did my snails intake that much calcium?
 
If your last test was within a month, I’d say it’s unlikely to drop 300+ in that time and is likely an error. Also, what is your magnesium? Mag affects Cal levels.
Magnesium has been pretty steady at 1300-1350

I was kind of figuring user error or bad test kit....

also getting ready to dose my tank for Alkalinity. My tank since new seems to be around 6, the last two times it tested at 6.2. I have some BRS soda ash, so I will mix that up tonight.

There’s no need to dose anything. Let the aquarium do its thing. Your wasting your time
