I didn't say it wasn't possible, others said it may not be optimal. I said I hadn't tried to do it for extended periods of time I know when my mag gets low I have problems and it shows in my corals. 1280 is a far cry from 1100.
I've used NSW on many of my system for a long time when I lived in SD. The mag is 1200.
I simply was pointing out that both like the waters of New Jersey, and the water of San Diego our parameters are less then ideal when compared to that NSW from a location that supports Tropical Reefs. While I have never personally tested the water of bali, fiji, or even flordia for mag..every article, or publication I've came across seems to claim they have much higher levels then 1100.
Also are you sure the aquariums water is testing at 1100? Depending the location the water comes from and it's proximity to other sources, or depth or it can very wildly.
Off the topic a lot of the issues with wild corals imop is simply how anal people are with husbandry when you run a zeo system it requires a much higher attention to details. I've had great success with Wild & Mari pieces and some failures, but I've been able to pin point the actions results in each failure and 90% of the time it was a result of a change in alkalinity but that's a whole different topic.
