What is Ammonia…..
basically caused by excretions from your fish as a waste product, it
can also be caused by overfeeding and rotting material likely to
cause ammonia gases. Ammonia is extremely toxic to the inhabitants
of your pond, but normally it is broken down into less toxic nitrite
by the beneficial bacteria in your pond filtration system.
Why test for
present in your pond water is very likely to cause health problems
for your fish, the more concentrated the ammonia then the bigger the
problem….toxic ammonia can build up in ponds where there are
insufficient beneficial filter bacteria to cope with the total waste
from all the fish in the pond. This can arise in a new pond and also
when any new fish are added to the pond. A problem can also arise
when the filter bacteria have been disrupted. This can happen for
several reasons….filter cleaning…mis-dosing of pond medication in
certain circumstances….over feeding….
the correct ammonia level…
most sought after level is zero, it is possible if you tested your
pond every day (which is not practical nor would we recommend) there
can be a small reading…this can be caused by feeding the day before
or right down to temperature, but you have to be sensible…..the
optimum ofcourse is zero PPM.
What to do
if the Ammonia level is wrong….
If a level of
0.2mg/l PPM is recorded for no explanation then add a good quality
filter booster. If a level above this is recorded then a substantial
water change is essential. We would recommend that you change 25% of
your pond volume…..for 0.5 – 1.0mg/l PPM ammonia and 50% to 75% for
ammonia above this. Zeolite can be added as this will act as an
absorbent in your pond filtration. It would then be advisable to
check the other vital water parameters, especially Oxygen, pH an
