What are the Benefits of Using an Airstone in my Aquarium?

A very popular misconception is that if you’ve got a good filter, you won’t be needing an airstone. Even if you do have a good filter, adding an airstone will circulate the water more effectively.

To say the least is the water circulation that’s created in the tank when the air stone starts functioning. When the bubbles rise to the surface of the water, they increase the water flow as well as the oxygen in the water.

Naturally, the increased circulation prevents the water from being lifeless.

Also, If the airstone used in your aquarium looks good or lights up when connected, it may add a nice sense of decoration to the aquarium. So you could actually add a few more, later on.

How Do I Install my Airstone?

An airstone is absolutely useless without an air pump. So, to start with, you need to get yourself a decent air pump that’s the right size for your airstone.

Usually, you’ll be needing one ranging from 2 to 5 watts. But as often it all depends on both the size of your aquarium and the type of airstone you’re going to use.

Once you’ve settled on an air pump, now soak your airstone in water for at least an hour. Always make sure to check the instructions, as some airstones require longer soaking .

Other equipment you’ll be needing are air tubes and a T-shape connector. Usually, the air pump has 2 outlets. So if you’re only installing one airstone, you’ll need to connect both ends of both air tubes to the air pump using a T-shape connector. This way you’re converting twin outlets into a single outlet.

By now you should have your airstone ready to be connected to the air pump. Simply connect the air tube coming out of the airstone to the T-shape connector that you’ve installed to your air pump.

You could add any decoration to your aquarium to cover your airstone if you prefer, and you’re good to go.

Where Do I Put my Airstone?

Airstones are typically placed at the bottom of the aquarium. However, there’s no specific spot for them. It all depends on both the size of your airstone and aquarium.

It’d be best if you place your airstone in the middle of your aquarium’s decoration and plants. By doing so it doesn’t bother your fish while swimming.

Also, make sure to place the airstone away from the filter. As you don’t want the bubbles coming out from the airstone to go right into the filter!

That would make the airstone almost useless.

How Do I Clean my Airstone?

Just like your aquarium needs cleaning, your airstone does as well. Below, I’ll be guiding you on how to clean your air stone in detail in 8 steps.

It’s best advised that you check if your air stone needs cleaning every 2 to 3 months. It’s also recommended that you clean your whole aquarium at the same time as well for best results.

Remove The Airstone From The Aquarium

First of all, turn off, unplug and remove the air stone from the aquarium and out of the water. Take off any rubber end pieces hanging on to the air stone. If some of them seem to be stuck, slowly move them up and down and twist them around until they come off.

Prepare Your Cleaning Solution

Now prepare your cleaning solution: Measure 30 mL of bleach and add to it 270 mL of water. Continue combining this ratio of water and bleach until you have enough liquid solution to clean all of your airstone parts.

Clean the Airstone

Soak in the airstone parts into the bleach solution for 2 to 3 hours. You could soak in with them any tubes you need to clean as well. After waiting for that period, gently move them around to make sure no dirt’s still stuck on any of the pieces.

It’s very important to wear rubber gloves before your hands touch the bleach.

Rinse and Dry

Now gently rinse the parts you cleaned using warm water, and let them air dry for another 2 to 3 hours. I wouldn’t risk towel drying them, as they might break.

Re-installing The Airstone

Time to re-install your parts together! Gently put 3 drops of silicone on to the edge of the airstone tube. Then install and secure the rubber end pieces that you removed earlier back in place.

Now place the rubber end pieces back on to the tube and squeeze a bit to make sure they’re well placed. Use a damp cloth to remove any extra silicone that comes out. Leave them to dry for the period specified in the instructions on the silicone tube. Repeat the same for all the remaining parts and tubes.

Re-install the air stone back into the tank, plug it in, and you have your almost-new air stone back in action!

Concluding

Adding an airstone to your aquarium isn’t an absolute necessity, but it makes a remarkable difference.

An airstone adds to the appearance of the aquarium, makes it more lively. The fish will enjoy it. And it also provides a healthier environment to them as it increases the water circulation, which in turn increases the oxygen in the water.

Determining the type and brand of the airstone you’ll purchase is a matter of personal preference. Some people don’t give the appearance of the airstone much importance, and just need it to do the job it’s done for. Others, want it to do both the air circulating and the decoration part.

I personally really like the DXCEL LED Aquarium Air Bubble Light. This airstone has both a good appearance and does a good job. It stays put at the bottom of the tank where you place it and produces a fair amount of bubbles for my fish. I also love the bright lights that come out of it. Overall a contender for the best airstone for aquarium!
