Airbubbles

[kosti]

Hello again...I have yet another question about my new project. There's tiny little airbubbles that are on the sides of the tank. I'm assuming it's a good thing from the filter bubbling the surface...but I just want to make sure. THANKS

That is normal in a new tank.

They'll go away soon and are not bad, it's oxygen.

You will also see them after every PWC...like everyone mentioned, it's normal and quite healthy.

Air bubbles are caused by the water being saturated and no longer capable of holding the disolved air. The colder a liquid is, the greater it's capacity to hold gasses. That is why it is common to see air bubbles shortly after water changes. Generally, the water that we put into the tank is slightly cooler than that of the tank and the agitation of adding the water forces more air to become disolved. Once the water is warmed up, it becomes supersaturated and air bubbles form.
