Too high calcium?

[DottyClown]

Small specks of very hard white substance have been sprouting out on the back glass. Only on the back, not on the sides or front glass.

Anyone have this same experience?

Is it due to too much calcium?

I've never test Calcium and have never dose any additives before.

Those are something called spirorbid worms. Google it.

You can scrape them off if it bugs you. After some time, they won't come back.
