Fish Crazy
I currently just vaccum the gravel when I am doing water changes which I try do twice a week...but the tank never seems to get clean. When I was much younger I used to clean the tank by removing enough of the current tank water to another tank..together with the filter and thermostat.....and with the remaining water I used to clean the tank and gravel, etc....once this was done and the dirty water removed...I used to fill the tank back up...treat it with a chemical that used to remove all the chlorine and metals, etc....wait a few hours until the tank was the right temp.....and then transfer the fish back into the clean tank. I never had any problems with my fish then but bare in mind I only had guppies, sword tails and a algae eater...which I believe are quite hardy fish. This was years ago....now I have been told that this should never be done and that only partial water changes should be performed to clean the tank.....that all the water should never be removed? Is this true? I just can't seem to get my tank as clean as before?
