1-inch round pond air stone. This is a high-quality, long-lasting air stone that provides vital oxygen to fish ponds, indoor tanks and aquariums in conjunction with an air pump. We use these stones for our koi ponds and fish tanks in-store and love them! Suited for 4mm airline/tubing.

These round air stones are sold individually and require an air pump and airline in order to function. You can check out our range of air pumps and airline tubing HERE


Pond air pumps ensure your fish are provided enough oxygen to thrive. On hot days, water absorbs oxygen at a slower rate, meaning that heavily stocked fish ponds can come under stress and in some cases, fish losses can occur.

Pumping in additional oxygen into the water can make all of the difference, in not only preventing such disasters but also ensuring that your fish pond biological filtration is working as efficiently as can be. This does wonders for your water quality. If you do not know which outdoor pond air pump is right for you, then please contact us and we can guide you in the right direction. We just need to know the size of your fish pond and the number and approximate size of your fish so we can point you in the right direction.  A good rule of thumb to remember however is that you cannot get too much oxygen into your fish pond water!
