Average rating of 4.6 out of 5 stars
The diffuser with the most power. Ideal because the air flows out centrally. The arrangement of the four stones ensures that the air flows out evenly.
We have also added the Asian market leader in air stones and diffusers to our range. Just as there are significant differences in quality between the original Hiblow and other air pumps, the same is true for accessories. Even at minimal pressure, you can achieve optimal results at greater depths with the diffusers. This also protects the membrane of your air pump and improves the oxygen uptake of the water. These are manufactured very differently from our standard products, starting with the material, continuing with higher firing temperatures and ending with the processing.
You can connect this block of 4 to a 9 mm hose. The block is simply placed on the pond floor. The air stones are screwed individually into the blue block. However, our normal 22 x 4 air stones cannot be used for this purpose as they have a different connection.
You can attach these air stones to a high-performance air pump (e.g. HiBlow 100, Hailea HAP series). Please note that the stones do not flow evenly, but the air moves from one side to the other, depending on the degree of contamination of the stone.
Monday to Friday: 9 a.m. to 5 p.m.
We only supply air stones in Hi Oxygen quality, which means that the air stones are fired at a temperature of approx. 1200°C. Although these stones are normally much more expensive, we are able to offer them to you at a very attractive price due to our high purchasing volume.
