I personally prefer somehting other than plasterof paris as well, and
use limestone (crushed) or aragonite sand (usually used in SW setups)
but never had problems with plaster of paris when I used it as long as
weekly water changes were made and the tank was not overloaded with
fish...........go for the crushed limestone
