We have 6 different saltwater tanks and I have a question about something that I've never encountered. The best way to describe it is that one of my tanks started getting hard white cysts all over the glass. They look like salt in its solid state but they are probably 5-6 times larger than a salt crystal. They are EXTREMELY hard to remove, and all of the water parameters check out perfect. Anyone have any idea what I'm dealing with???

spiral shaped ??

Nope, they are round-not perfectly, but close.
It looks like the salt used to make saltwater, only bigger???

i get them once in a while if i add to much calcium
