Hailea – Round Polo Ceramic Air Stones
- Round airstone will fit into almost any reservoir
- Porous stone creates many small bubbles
- Mixes and oxygenates your nutrient solution
- Partly plastic coated to help prevent being damaged
- Oxygenated nutrient solution improves root-health and turbo-charges plant growth
- Air pump and air line available separately
- Comes in 2 sizes – 3 & 4 inch
These Round Airstones come in 2 sizes and are circular pieces of porous stone, partly cased in plastic, leaving one side exposed. Typically, the small 3 inch round airstones go into small reservoirs, the 4 inch round airstones go into medium reservoirs.
An inlet nodule is located on the inside of the ring to allow the airstone to be connected to an air pump via a length of air line. When connected to an air pump, the air will exit the airstone through the many pores in the stone. When the airstone is submerged in water or a nutrient solution, the effect is that many small bubbles are produced and released from the surface of the stone. The bubbles create movement in the water or nutrient solution keeping it well mixed. The movement at the surface also greatly increases the amount of oxygen being dissolved into it.
Dissolved oxygen discourages anaerobic microbes which can cause root diseases and feeds oxygen to the friendly aerobic microbes. An airstone helps to keep your plant’s roots healthy while also providing oxygen for the roots to absorb. The Round Airstones are partly cased in plastic to help prevent damage to the brittle porous stone inside. Adding an airstone to your reservoir really does increase the speed of your plant’s growth and creates a healthier root-system. An airstone is very highly recommended for all hydroponic systems.
Connect the airstone to your air pump using 4mm pvc or rubber air line. If the air line is difficult to fit over the inlet, dipping the end in warm water should make job much easier. Always make sure that your air pump is at a higher level than the surface of the water in your reservoir to prevent water siphoning back into the air pump. Lower the airstone down to the bottom of your reservoir and switch your air pump on. The porous stone used in airstones is brittle and should be handled carefully to prevent breakages. Every so often, gently clean the surface of the airstone to maintain the air-flow and bubble production. Airstones do degrade with use and will become clogged and more brittle over time. Try to make sure you replace them regularly.

Did you know that you can drown your plants? It’s true. And it’s not the same as just overwatering a potted plant. When you overwater a plant, you risk issues like mould and root rot. When you drown your plant, it quite literally lacks oxygen, as a drowning human would.
That’s where air stones come into play for your hydroponic growing strategy. This article gives you the basics on what air stones are and why you need them. You’ll also find out precisely what role oxygen plays in hydroponics and plant health.
Here’s why your reservoir tank needs air stones.
What are air stones used for?
You may already be familiar with air stones if you’ve used them in fish tanks.
Air stones create tiny bubbles of oxygen in your hydroponic tank when the air is forced through the stone. The bubbles make the dissolved oxygen disperse more widely throughout your system. Typically, the oxygen bubbles are pushed through the system with an air pump, which we will discuss more in a later article. The stones themselves are submerged in the water or nutrient solution inside your reservoir.
Note that the stones themselves do not actually generate oxygen. They act as a mechanism to disperse the oxygen.
What is the role of oxygen in hydroponics?
When plants grow outdoors in soil, natural processes allow oxygen to penetrate the earth and get to the plants’ roots. For example, worms churn the dirt, which disperses oxygen, making it more accessible to the roots.
But why do plants need oxygen at the roots? The oxygen actually assists the process of nutrient uptake. When more oxygen is present, plants can better absorb minerals and even water. That means the air stones can make your nutrient solution more efficient. Without enough oxygen, plants are likely not to grow to their full potential, in part because they aren’t taking nutrients ineffectively.
In addition to aiding nutrient uptake, increased oxygen circulation around the roots also helps to prevent harmful pathogens from taking hold and making plants sick. The lack of pathogen protection from insufficient oxygen is directly related to plant nutrition. When there’s not enough oxygen, the plant doesn’t get enough nutrients, and when it doesn’t get enough nutrients, it produces stress hormones that make it less able to fight off everpresent bacteria.
Choosing an air stone
Air stones come in a few different sizes and shapes. It’s not hard to select one, though. Use smaller stones for smaller setups and larger stones for larger setups. As for the shape, pick one that roughly matches the shape of your tank. The most common shapes for these oxygen dispersers are rectangle or cylinder.
You can try a few different air stones and experiment with which shape and size will work best for your nutrient tank.
Air stones are not expensive at all. They’re a tiny investment that can make a big difference in the health of your plants. So come in and check out the airstone options at Gone To Pot Hydroponics.
“Look lovely in my fish tank , fish having fun swimming in and out of the bubbles , would recommend these , have purchased two rings and they look lovely in my tank”
“The product is not weighted so a lot of gravel is needed to hold it down in the aquarium, and the air comes out in a ring formation as hoped. Would buy this again.”
“Awesome product. Tried a few but prefer this type. Delivery was very quick.“
HAILEA is a dynamic and creative mechanical and electrical manufacturing company.
For more than 20 years, we have been constantly pursuing new technologies and superior product quality. “Respect for individuality” and “emphasizing the concept of each individual” have made HAILEA a creative and free and open corporate culture. Now, HAILEA has become a world aquarium equipment, aquaculture equipment, garden supplies, industrial air pumps, electronic products and tea set tea art. Active participants and promoters of R&D and production of supplies.
HAILEA has been dedicated to creating outstanding brand performance, and it is this spirit that has always supported the development of the brand HAILEA. Excellent brand performance is not only the tradition that we have established for quality products for many years, but also represents the excellent performance of our products, which is the honor that consumers give us.
Since the initial production of aquaculture electromagnetic air compressors, HAILEA has been paying attention to “changes”. Looking back at history, in the process of changing the times and people’s life concepts, HAILEA is always able to grasp the opportunities of change, and take the lead in developing and producing new high-quality air pumps, submersible pumps, electronic products, tea and tea supplies, etc…. HAILEA people are looking forward to The next change is also trying to create new changes.
At the same time, HAILEA actively fulfills its social responsibilities as a corporate citizen and actively explores ways to protect the environment and save energy. Every product of Haley pays great attention to resource utilization and environmental protection from design, materials and production. We believe that “there is no long-term future for the company without environmental protection.” Based on this understanding, we have developed and introduced energy-saving temperature memory systems, multi-layer biochemical wastewater treatment systems, and international green fluorine-free refrigeration technology applications, and will continue to increase in the future. In the environmental protection of products, Haili products have reached the international advanced level.
HAILEA is still very young and still in the early stages of entrepreneurship, but I firmly believe that through unremitting efforts, HAILEA will become a strong company, which can help the society more helpless and need help.
