If you are in academia, order some from a chemical supplier. I think half
a kilogram is only around $15-20 at the most. Seems as if you can find a
bulk chemical place you could get a 50 lb bag for probably the same price
as the high grade chemical stuff.

A fellow from Germany keeps saying something about it being considered a
pollutant there. Have never followed up on it though.

You should always have some type of biofiltration running anyway, unless
you are setting up a planted jungle. I've used it for years and never had
a problem, but I've always had filters too. I wouldn't be too worried
about it though.
