Magnesium lvs too high causes of stn?

I had the same problem in my tank. After a few large water changes the stn has stopped and colors are coming back to normal. Mine got so high because I was already keeping it around 1400 and my dosing pump didn't shut off and dumped a fresh gallon of mag into my tank.

I agree. High Magnesium has never hurt my tank in any visible way that I can tell.

I've had high mag wreck havoc on my tanks.. montis go first, acros do not like it. I was off the salifert kit it was a nitemare took almost a month to get things back in order.
Thanks for the advice, my Mg lvs got so high due to negligence, didnt monitor e lvs as i was totally pre occucpied with KH and Ca.
As for me my Birdnest were the first to go, followed by millis and now montis.
If mentioned that Mg wouldn't cause stn, then might have caused it?

no mag will, BN's will shows issues right away to. people who claim mag wasn't an issue got lucky or didn't keep it that high for very long.
I think all views contributed here on the effects of high Mg should be considered.
Imho, the effect of high Mg should be examined in the light of whether the elevated Mg level happens during a short period of time which constitude a 'Mg shock' to the SPS versus one which the Mg level been slowly raised over a long period of time (wheather knowingly or unknowingly ) which the corals has developed the ability to cope with such high level.
It is almost a certainty to say that any form of shock is a sure way of stressing SPS. If the shock is both too large a scale and happens within a short time, the result is most likely an irreverible downhill of SPS resulting in total death.
However, it is very likely that given a chance to adapt over a long period of time where the change is incremental, SPS could exhibit an incredible ability to adjust itself to tolerate such incremental change. So those who has manage to keep Mg at a very high level such as 1800 could most likely be the case.
However, i believe there would be a 'critical level' beyond which SPS would no longer be able to cope further.
That said, I do think it's still best to keep Mg at level close to the natural sea level for one simple reason. It's easier to get your next new SPS collection acclimatise and adapt to your tank water thus increasing the rate of survivability.
And yes, bridnest and montis are usually among the first few sps specimen to show distress in the case of Mg shock.
