Welcome to the AGA. It is very likely that it is due to the gases in the water that you are putting into the aquarium and is not a cause for concern. High gas levels in the water will mean that the water reaches saturation sooner and the gases being given off by the plants, unable to dissolve into the water, will present as bubbles. You can ask for water supplier for a copy of the ater quality report that they are required to produce and make available under EPA regs. This will show most of the important things. And you can ask the water supplier what gases are dissolved in water that has been standing in the pipes for any length of time. Usually it is just CO2 and O2. How much gas is in the water depends on the pressure the water is under. When water comes out of the tap, it is at atmospheric pressure and no longer under the water system pressure (about 40-80 psi) so some of the gas that was dissolved while the water was inthe pipes is released when the water comes out of the pipes. You may have seen that sometimes tap water in drinking glass look very cloudy at first with minute bubbles but clear us quickly as the bubbules rise to the surface are break into the atmosphere.
