Fish Fanatic
I have just taken a test results and found the reding were very high. I looked to see what the problem was and the filter had packed up. I think the filter is 'dead' so i got a new one. Should I place some of the tanks gravel and water in a different tank with a undergravel filter and place the fish in there. I could then place the new filter in the main tank and let it become colonised.
