Must admit i've never used an air pump in my planted tank, not sure why you'd need to.(not flaming)
At night plants take in O2 and give out CO2. In medium to heavily planted tanks this could cause high levels of CO2 which can lead to problems (like gasping at the top of the tank, which i began to experience and then it stopped with the addition of an airpump and airstone during the night). I'm sure your aware fish need O2 rich water.
