1. All-Around Best Airstone for Aquarium - Hygger Aquarium Air Stone Kit Review

This product blew us away as soon as we plugged it in with the sheer amount of bubbles it was immediately able to produce. This product produces an intense wall of air bubbles which do a wonderful job of circulating the water as well oxygenating it.

The beauty of this airstone’s design is that although it creates an overwhelming amount of bubbles, they are not powerful enough to the point where they would disturb or be too disruptive for your fish. They help in the circulation of water but they do not displace it enough for it to be unsettling for your fish and we think that’s a very admirable trait.

Buyers’ Guide

What are the benefits of having an airstone or airstones in my aquarium? 

Airstones are a piece of aquarium equipment that isn’t absolutely necessary for the successful running of an aquarium but considering the number of benefits they have, you should definitely look into getting them for your aquarium if you can. Some of the benefits of having an airstone or airstones in your aquarium are: 

  • They help oxygenate the water. Airstones are very effective at helping aerate the water. If you feel that your fish are becoming stressed, it may definitely be due to a lack of oxygen. Getting an airstone may very well help alleviate these symptoms.
  • They help in water circulation. Water circulation is important because you don’t want the water to stay at the same place in your aquarium as this can result in pockets that start lacking oxygen. These pockets can eventually end up producing hydrogen sulfide which can be very toxic to your fish. Air stones do a great job of kicking up the water near your substrate up to your filter where it can be swept up and filtered.
  • Airstones are great for aesthetic purposes. The sight of gently produced bubbles can be very calming and pleasing to look at. 

How does an airstone work? 

Airstones come in many shapes and sizes and they come with small air pumps that work consistently to produce tiny and dense air bubbles within your aquarium. These air bubbles increase the surface area of the top surface of the water and make it possible for the oxygen in the air to infuse much more effectively with your aquarium water. 

What are some aspects to consider when purchasing airstones for my aquarium? 

You may be confused about which airstone product would best most suitable for you. In that case, the best way of narrowing down your search is to think about the different aspects of airstones in terms of how they work and what kind of bubbles they produce. Some common aspects to think about when purchasing airstones for your aquarium are: 

  • Ease of Installation and Use 

Most airstones come in simple designs that are relatively easy to set up. This is definitely something you should strive to look for as you don’t want an airstone that is cumbersome to install as you don’t want to spend too much time installing secondary aquarium equipment. 

Secondly, the airstone should be easy to use. We definitely recommend that you get an airstone that just starts working as soon as you plug it in. Many airstones come with gimmicks such as a remote control to control the speed and size of the bubbles, etc. and while these may seem like attractive features, they often don’t work right and are confusing to use.

  • Price 

Keep in mind that airstones are secondary aquarium equipment and there’s no need for you to go overboard when it comes to buying them for your aquarium. Expensive airstones really are not worth it and you can get the same performance in relatively cheaper airstones so we definitely recommend you to be wary of overly expensive airstones. 

What are the different types of airstones? 

The different types of commonly found airstones in the market are: 

  • Flexible Bubble Walls

These are made from a flexible rubber material and they come in different lengths. They are very easy to handle and you can attach them onto your aquarium in a number of different positions as you please. They have tiny holes in them which enable them to produce the tiny bubbles using an air pump attached underneath. 

  • Bubbling Ornaments 

These are usually brightly colored and play a dual role as decoration pieces inside your aquarium as well. Not only do they produce bubbles, but you can also use them to hide aquarium equipment such as a filter or heater. 

  • Bubble Wands 

These are much narrower and lengthier than other types of airstones and they produce large walls of air bubbles that give your aquarium a very unique aesthetic. 

  • LED Bubblers 

These are airstones that come with an LED light built into them. This LED light can often change colors and the bubbles that are produced look extremely beautiful with the LED light shining on them. 

Where are airstones normally placed inside an aquarium?

Airstones are normally placed at the bottom of your tank. Make sure that your aquarium airstone is at a distance from your fish tank filter. This is because your air bubbles won’t really do much if they are immediately swept up by your filter. Not to mention, they could also end up ruining your filter

Frequently Asked Questions (FAQs)

Are high-end airstones really worth it? 

Not particularly. As we’ve discussed earlier, you can definitely get the same level of performance out of relatively cheaper airstones that you would from expensive airstones. Expensive airstones might have some other features that you may want such as bubble size customization, lighting, colors, etc. If you have the money to spend, you can definitely get expensive airstones for these features but in terms of functionality alone, there’s really no need for it. 

How often should I clean my airstone(s)? 

This depends highly on a number of factors such as how many fish you have in your aquarium, how much food you give them, how powerful your filter is, etc. As a general rule of thumb, you should check your airstone every other week to see if it requires cleaning. Most airstones usually need to be cleaned every 3 – 4 weeks or so. 

How do I clean my airstone(s)? 

Start by shutting your airstone off, detaching it from the air pump and removing it from your aquarium. 

Next, take a clean bucket and make a mixture of water and bleach inside it. It’s essential that you use a very low amount of bleach, a ratio of 10 parts water to 1 part bleach is generally the way to go. Once you’ve made this mixture, place your airstone inside and let it soak for a minimum of 3 hours. 

After these 3 hours, take out the airstone and run it under warm water to knock loose any large pieces of debris or waste. You can use an old toothbrush to really get in there and clean out all the gunk and dirt. 

After this, let the airstone dry out for a minimum of 2 – 3 hours before placing it back inside your aquarium. 

Can there be too much oxygen in my aquarium

Yes. Too much oxygen is definitely a risk factor that you should be wary of. Too much oxygen in an aquarium can lead to something called lethal gas bubble disease which is characterized by small bubbles on your fish’s skin and around its eyes. This disease can be highly uncomfortable for your fish and in extreme cases, it can even be fatal. 

My airstone is producing bubbles that are too disruptive for my fish. What can I do to fix this? 

You should check your air pump to see if it has the option to slow down the flow rate. If it does, that’s great, if not, you can opt to either get another lower-powered air pump or you can try to partially block the opening of your air pump so it’s flow rate is not as intense. You can do this by blocking the opening with a sponge or with a partially cut piece of a plastic water bottle. 

What are some of the most reliable brands when it comes to airstones for aquariums? 

Some of the most reputable and reliable manufacturers of airstones are: 

  • Hygger
  • Pawfly
  • Marina 
  • Penn Plax 

What are airstones normally made out of? 

Airstones can be made out of many different materials but they are generally made from porous, permeable substances such as stone, hard plastic, wood or sand. 

Should I wash my airstones before I place them in my aquarium? 

Yes. It’s definitely a good idea to wash and rinse your airstones before placing them inside your aquarium. If you’re setting up a new aquarium, then you can definitely wash them with regular tap water since you’re going to be cycling your aquarium anyway. 

What’s a safe way to wash my airstones before placing them in my aquarium? 

As we mentioned earlier, you can wash your airstones with regular tap water, dry them out and then add them to your aquarium if you’re just setting it up. 

However, if you’re adding them to an already established aquarium, you should clean your airstones with the aquarium water. You can do this by removing some of the aquarium water into a clean bucket and then rinsing your airstone in it. 

Do airstones work effectively in saltwater aquariums as well or does the salt eventually build up and clog them?

Yes. You can definitely find airstones that are specifically made to operate inside saltwater aquariums. They are specifically designed to prevent the buildup of salt in their openings. 

Final Verdict

Airstones can really enhance the look and functionality of your aquarium so it’s essential you find a high-quality one that is able to push your aquarium to its fullest potential. 

After months of testing and contemplation, we’ve concluded that the Hygger Aquarium Air Stone Kit is definitely the best airstone product that we had the pleasure of testing. It’s insanely effective, it works longer than most of its competitors and it’s also modestly priced.
