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.
