[APD] Re: Sulfates



Ed Dumas asked:
	Is there a dangerous limit with Sulphates in an aqaurium, to either
plants or fish? I assume that small quantities are okay, but at what point
is it possible to do harm? Is there a test kit for sulphates? If I know that
point, I can know what level to stay well under.

I don't really know what the upper limit for fish is, but the tap water here
in west Texas contains 380 to 400 ppm SO4. I dilute it with RO water because
the total hardness is 570 to 600 ppm (33 to 43 GH) and I keep cardinal
tetras, which prefer softer water. A lot of people here do use straight tap
water, and don't seem to have any trouble, except for the white scale it
leaves.

Maybe I'm a wimp, but it still makes me sick to drink the stuff, and I've
lived here for 25 years.
