white spot on tank glass

[xa]

Ok just today I've see some white spot forming on my 35 gal tank. (no fish, only hermit) Is this a poissible a ich forming? (ok, I know it might sound weird)
My water quality is as follow: PH 8.02, no ammo, no nitrate, nor nitrite. Salt is at 1.023 (around there) The tank is up and running for almost a month. Thanks for your time.

Yup. It even look like salt thats forming when the water evaporates. But thx for your help. It does come off very easy when I scrap them with a mag.

i have these spots too, at first i thought they were baby snails, but they never grow. I am curios if these are especially dangerous because i have quite a few. I've had them since i set up the aquarium 3 months ago. My friend has them too.
thanks

Ok if its calcium deposits. Does it mean the calcium lv is too high?
