It may be chloramine in the water supply, the water companies put in an "emergency" dosage if there is any breach in the integrity of the water main (burst main, main repair etc.). The conversion of the extra ammonia will deplete the oxygen from the water, even if the filter isn't over-whelmed.
There was an absolute epidemic of this last year after the freeze with peolpe losing £thousands of L number plecs etc.
The more water they changed the worse it became. Do you have a non-tap supply you could use? like rain water? I just bring enough rain-water in for my next 2 water changes to allow it to warm to room temperature. This would also tend to out-gas any extra CO2, if you were worried about fluctuating CO2 levels.
If you use CO2 I would turn it off until things settle down, as a high CO2/O2 ratio is likely to stress the fish. I'd also treat any tap water with Prime or Amquel as these will complex the ammonia from the break-down of the chloramine.
cheers Darrel
