I remember reading something on RC about it and it was quite a bad thing to have in the tank. Gypsum is very caustic and not a good thing at all to use, and I think anyone who puts it in there tank for Ca is nuts as it is not a soluble Ca source. anyways another problem with Gypsum is the dust is so fine it gets into everything and will destroy motors of vacuums or maybe external pumps. if you are really bent on doing this I would tent your tank and use a outside air source for the tank.

"Formed by the evaporation of saline deposits from seawater, gypsum is an abundant mineral found in all parts of the world. Some of the most notable national deposits include California, Utah, Colorado, New Mexico, Ohio and Michigan. Gypsum is also commonly found in France, Switzerland and Mexico, and other parts of the world.
Due to its unique properties, and because it is non-toxic, Gypsum is used in a seemingly endless number of products including: food additives, beer brewing, casting plasters, toothpaste, medicines, and as a soil amendment in the agricultural industry." hope this helps...

The dust created from dywalling is not from the drywall anyways, it's from the compound when you are mudding and taping. The compounds are not made from the same stuff as drywall and have ingredients that are not good for you so likely not your fish either. Better safe than sorry. My two cents.
