If you need to raise and maintain higher levels of oxygen in the water you supply to your plants or fish, you will need to use an Air Stone and air pump to provide a gentle flow of bubbles into the water.
We have a great selection of air stones that can be used for hydroponics systems and water storage tanks and they can also be used for aquariums.
Top Tip
Over time a build-up of salts from your nutrients will appear on your air stones, this can be removed easily by soaking them in a solution that contains liquid oxygen or a gentle brush with a toothbrush will do.
