Could someone advise me please if I would do any damage to the compost heap
if I poured the waste water from an aquarium onto it after cleaning out the
filter. The water would be slightly acidic and would contain amonia,amonium,
trace elements of nitrates, some nitrites and de-nitrifying bacteria in
smallish amounts. The ph would be between 6.5 and 7.2. I would be discarding
about 20gallons per fortnight, too much for the heap but would a few gallons
do any harm.

No problems at all. And the nitrates and ammonia would be good for the
heap.
