How To Set Up Bubbles In A Tropical Fish Tank Aquarium

One feature of tropical fish tanks which is widely loved, not to mention being practical and beneficial to the running of a healthy aquarium are bubbles!


We explain the reason why you might need bubbles in your fish tank in another article however I wanted to explain how to actually do this and what equipment you need to achieve this as well as how to set it up.

Here is the shopping list of things you will require:

  • Air Pump
  • Air Line
  • Non-Return Valve
  • Air Stone

Instead of an air stone you may chose to use some sort of ornament which bubbles will come from however we will cover this with the air stone for the sake of this guide.

The order in which you should plug the equipment in is:

Air Pump Outlet -> Air Line -> Non-Return Valve -> Air Line -> Air Stone


The above diagram should give you more of an idea of what things should look like. The non-return valve is one of the most important things in this set up as it will prevent back syphoning from the tank and the tank emptying out through the air line. These are only essential if the air pump is to sit below the aquarium however for the sake of a couple of pounds, it’s a very worthwhile investment.
