Why are There so Many Bubbles in my Fish Tank

Hi, their aquarium enthusiast. We hear that you are having problems with the sudden infestation of your water tank with lots and lots of bubbles. You are most likely pretty confused, and want to figure out what is causing this.

Bubbles can be an annoyance, especially after you spent so much time preparing your fish tank to be exactly how you want it. Luckily, in today’s article we will cover what is most likely causing the bubbles, and we will provide steps to help prevent bubbles in your fish tank.

Why are there so many bubbles in my fish tank?

Below are the main reasons why there are so many bubbles in your fish tank:

Aeration

If the bubbles appeared right after you started to fill your tank up with water, then the air already present in the tank is the likely cause of them. We all must be aware of the fact that all empty things have air in them, and those air molecules can get trapped once you start filling up your aquarium with water. Those air molecules can get attached to the glass panels of your aquarium and can jeopardize the beauty of your aquarium. Aeration can also cause white stringy stuff in your fish tank.

Solution

Fortunately, air bubbles caused by filling up your tank with water are the easiest to get rid of. All you have to do is wait as those air bubbles will eventually rise up to the surface and pop out of existence. These bubbles will most likely disappear after one day.

Don’t want to wait up? Well, no worries, grab your algae scrubber and pull those bad boys to the surface yourself.

Bubbles caused by the filter.

The filter present in your tank might seem completely innocent, but it can also contribute to creating bubbles on the surface of the water in your fish tank. Normally it is really hard to figure out if the bubbles are actually caused by the filter or something else; as such, bubbles tend to be spread out on the surface of the water. Watch your filter nozzle carefully, and if just a single bubble appears on the nozzle in a minute or so, then the filter is most likely your culprit.

Solution

In most cases, bubbles formed by the water filter do not translate to a faulty filter, as the problem usually lies with the nozzle of the filter. Air bubbles are formed around the nozzle when it is in direct contact with the air. Therefore, an easy way to solve this is to lower the nozzle into the water level. You can also increase the water level so that nozzle is fully submerged in the water.

Air bubbles caused by Water Heater

Now here is a factoid for you, cold water has the capability to store more oxygen molecules than hot water. Therefore, if it seems that bubbles start forming around your water heater right after you turn it on, the heater is probably the culprit. The bubbles form because that previously cold water is now losing its capacity to hold oxygen and that released oxygen appears in the form of air bubbles.

Solution

Bubbles of this sort are nothing to be worried about as they tend to fade away within an hour.
