My bottle only lists Magnesium sulfate on the label. It's an old bottle though, maybe it's changed...?

EDIT: Here's a pic of a label from 2013 and yeah it looks like magnesium chloride now:

The label has seen many changes over the years , probably because everyone wants to know the magical ingredient and they are pressured to post what's inside

They say the ingredients haven't changed just the way they word it lol


I'm not a fan of tech m fwiw; )

Yeah, I saw that...I don't believe it. I'm not a fan either. I use Fauna Marin Magnesium chloride and add a sniff of Epsom.

I'd check your test kit. You'd be precipitating calcium to less than 420 ppm if your mag was that low I think.

Actually I was getting hard white bumps on my glass, if that is what you mean. I had just been cleaning them off.

What I mean to say is your calcium should not have been that high with such a low magnesium. So either one of the test kits was probably inaccurate. Did you check the expiry? What brand were you using?

Calcium precipitation is more likely to occur near a heat source, like pumps or heaters, but could also occur directly in the water column if conditions are right. Unless your room temperature is higher than the water temp, the glass is the last place I'd expect to find it. Those were probably some sort of snail you were scraping off the glass
