Hi dempsec1, it's not a problem because biological filtration is being performed by the plants. In a well planted tank, bacteria are just not that important. In fact they require a lot of oxygen to change NH4 to NO2 to NO3, unlike plants which use CO2. So to answer the question it might effect the bacteria, but in a way that would be considerably better for the overall health of a planted tank. It's just not something we need to worry about.
