The amount of bacteria in a tank depends on the rate of fish waste. Monthly water changes will result in more bacteria due to the ammonia released by the waste. Nevertheless there will be enough bacteria in the tank regardless of monthly or weekly changes. The issue is more with the amount of dissolved organic waste and other waste floating around. Filtration and beneficial bacteria do not pick them up and get rid of them. They stay in the water and it's not healthy for the fish. Signs will not show up immediately on the fishes appearance, but they will over the long-run. Over the long-run, most people don't realize how good or bad their fish looks unless comparing to another tank with similar fish that gets weekly water change.
Often, there are members here who claims that their overstocked tank is well and healthy, regardless of whether they do weekly or monthly water changes. After some time, the result is always the same - bad water quality (first sign is high nitrate reading) and/or dead fish. Even a good planted tank won't be able to soak up all the waste from these types of tanks. SW
tanks are able to get away with good water quality in an overstocked tank with the help of Skimmers, macro algae, and ability to house anaerobic bacteria.
