TEST RESULTS of Deadly Pond Water:

O.K. I tested the pond water which killed a goldfish within two hours.
Please note that this water has been sitting there for over 48 hours,
so it is not exactly the same water that killed the fish.

The pH measured at 7.7 using Tetra test kit, the nitrate measured at
perhaps 1 PPM (color between zero and the 2 PPM color on the color
scale) using Salifert test kit, the total ammonia measured at between
.25 and .5 PPM using a Tetra test kit.


-- that amount of amonia is deadly if i remember correctley

Tom,
I don't buy the ammonia theory.
0.25 -0.5 ppm ammonia is not that severe, certainly not bad enought to kill
so quickly.
If it were no fish would ever survive a cycle, right?
Temp & pH factor into toxicity of ammonia, but extrapolating from table in

pH of 7.7, even at 83F, 0.5 ppm is not off the chart, is it?
Count me in the leaching septic or fertilizers camp
