Key Features
Invisible Air Stone Kit
The hygger air stone feature is invisible, durable, and steady to bubbles. Optimal for aerating fish tanks and livening up the aquatic environment. The air stone is made of high-quality acrylic, and it is easily hidden under the water. The unique EVA material is used for aeration, which will not get clogged and can continue creating constant bubbles. The air stone kit is perfect for oxygenation in freshwater and saltwater/reef aquariums, hydroponic, or aquaculture.
Invisible and Beautiful
The acrylic material makes the airstone invisible in aquariums, and the stainless steel blocks keep it steady at the tank’s bottom. It will not move when creating beautiful and fantastic bubbles for your aquarium, and it is easy to hide.
Not Easy To Be Clogged
Compared to the traditional ceramic air stone, the innovative hygger air stone uses a special EVA material to create bubbles, which is more corrosion-resistant. No matter how long it is used, it will not get clogged. The airstone bubbler is durable and has a long service life.
Ultra-high Dissolved Oxygen
The bubbler for the fish tank has a double aeration ring, which can quietly produce a good amount of dense bubbles. It is great to add oxygen to the aquarium and increase oxygen levels. Ideal for freshwater, seawater/reef aquariums, fish tanks, hydroponics, and small ponds.
Steady Medium Bubbles
The air stone discs are well-built for constant bubbles. Each bubbler produces several medium bubbles bursting steadily to increase oxygen aeration in the tank, so the airstone brings a high dissolved oxygen rate for aquarium inhabitants. Nano pumps of 2 W can easily drive it.
Various Air Stone Kit
There are 3 kits for different use: 1.7-inch/2.3 inch/3.1-inch air stone set
Includes 6.5 ft and 3/16″ airline tubing, a complete standard aquarium accessories set for most air pumps, and helps build the basic aeration setup in aquariums.
Easy to Clean
There is no need to clean the stone with disinfectant, brushes, or clean it frequently. Just take it apart and wipe it gently with a soft cloth or rinse it under the tap.
Usage Tips
1. Driven by air pumps of more than 2W, the air stones can produce nicer bubbles when connected with more powerful air pumps of more than 2W. Please choose a proper air pump according to the size of your air stone.
2. Comes with a diameter of 4 mm diameter air pipe, and the length is 78.7 inches/2 m.
3. If the bubble is large, please use the attached pliers to tighten it to the most.

Recently, I purchased AC Ultra Quiet Air Pump (HG095-4W) which I really like, but frankly I was not happy with the air stones that came with the pump; therefore, I replaced the air stones with the Invisible Nano Air Stone (HG049-45MM). Hygger makes three versions of this air stone with the HG049-45MM being the smallest at 1.8 inches. I like this air stone so much that eventually I’ll purchase a second pump and air stone for my other tank. Please the attached video which demonstrates the air stone’s performance when the pump is working at its lowest versus the highest point.
Extremely adjustable, heavy and well made. It comes with plenty of air hose and a check valve. All very good quality. I am looking forward to years of service from this aerator.
This air stone is great. The bubble size is adjustable with an included tool, which allows it to be used in practically any tank. I use 2 of these in my 75 gallon and this generates much more surface agitation than the traditional air stones they replaced. I have only had these in the tank for 1 week, so I have not had to clean them. I do like the fact that if they develop algae, it’s super easy to clean them as needed.
Delivers beautiful air bubbles
Good bubbles, buried it in coral and it didn’t clog or anything
Stunning air stone! Unique looking design can be easily hidden in my fish tank.
