Salt waterlogged!!
The white fluffy stuff.
There is the issue of what is better for captive conditions/realities versus reef conditions. Many examples (O2, DO levels, tolerance of nitrate and phosphate levels, etc)
Re: calcium... I'd simply remind folks that both Calcium and Alkalinity (and magnesium for that matter) do not have to all be on the high end of the acceptable range concurrently. Rather, it is my strong opinion (and that of others) that high Alkalinity and moderate calcium are better for captive conditions.
Specifically... 350-425ppm is the "ballpark" for Calcium and 8-12 dKH for Alkalinity.
In a perfect world... I'd like to see aquarists with garden reef aquariums have their Alk at a solid 11-12 dKH while calcium was kept stable at an average of 375ppm or not far from it (+/- 25ppm)
I seem to recall the (truly) esteemed Dr Randy Holmes Farley making similar comments about Calcium not needing to be as exceedingly high as (too) many sps enthusiasts recommend.
WOW! this seems to be pretty vital info for any reef keeper.
Cool... we have some of those here too: http://www.asira.org/aquariumbasics
However, I have yet to put those in a printable format. I'm hoping to get a few more experienced hobbyists to review the information first before I make actual "care sheets" our of them... if anyone is interested in helping out, please feel free to PM or email me.
