Had just completed 30% water change and turned filter back on. Because I've been insanely busy I hadn't cleaned out the filter media in ages and it spewed a bucket-load of filth into the tank. Nitrates off the chart and water like mud. I've just done another 30 - 40% change and put a second filter in - no beneficial bacteria, just to take some solids out of the water (and cleaned the first filter out). How soon before I can do another water change? 6 foot tank and filter output is 2000 litres per hour. Any advice greatly appreciated.
