Magnesium?

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

test are Salifert and dont expire till 2017 and 2018.

Now at Mag 1350, Cal 460, and KH 9.6

there would have been a water change and the magnesium would have been low in the salt mix , there isnt anything else in a reef system that uses magnesium besides the animals themselves and mg consumption is about %10 of calcium or about 1-2ppm per day.

good luck , always test your new salt and if need be bring your mg up

Now that I have my magnesium up to 1300 alk at 8.6 and calcium at 420 all my hammer and torch are back extending and looks like one of my hammer is growing another head.

I thought water changes would fix things but I should have realized if your salt is low more of the same won't fix it.

Thanks for the tips all.

Exactly! Glad to hear things are on the mend!
