Ugg!  First ammonia is not toxic, now nitrate is not toxic at 100s of
ppms!

Either my aquarium education is full of hearsay or I'm getting old.
Maybe both.  I do have to say that I've read many observations of fish
and invertebrate behavior changing with respect to nitrate
concentration.  40 ppms sticks in my mind as being a point where many
Tanganyikans will stop spawning.  I realize that reefing is a different
story but I'm sure my reef would not look good with 100s of ppms of
nitrate floating around.

Cheers,
Chris

Nitrates at several *hundred* ppm have been shown to be totally 
non-toxic. Many plant nuts have to *add* copious amounts of nitrates to 
keep their aquatic gardens growing and looking good. 30-50 ppm are 
typical minimal needs for a CO2, high-light tank. Gross overdoses don't 
seem to bother the fish.
