Tested my tank tonight for the first time in about 3 weeks,
pH 6.0, nitrates nil,, nitrites nil ammonia .25 -.5.
Shock, horror!! Have done a 30% water change tonight, also did one on Monday night, tested again, still at .25.
Do I continue on changing it nightly until it goes back to nil. At this stage a 30% change requires me to bucket 150 litres of warm water through the house. Or do I do a bigger change tomorrow, if so will the pH rise as the water comes out the tap at around 7.6.
