Hi..

By accident I once subjected a tankfull of plants and
Ammano shrimp to 200ppm nitrate for 3 week. No ill effects
whatsoever.


200 ppm == 200 milligrams per litre

Richard, sorry but what shall it show us..?

Amano shrimps are brackish shrimps and brackish animals are
well known to be very very very tolerant relating to high
leveled NH4+, NO2-, NO3-- ..!!!


At 0.5ppm NH4+ half of my ammanos died.
