Efficient Airstones for Compost Tea & Hydroponics
These efficient, micropore airstones help oxygenate and circulate water in your compost tea brewer, hydroponic system, or reservoir. Their fine-pore design creates a steady stream of bubbles to boost dissolved oxygen and support vibrant microbial life.
Use multiple airstones to reach your desired aeration level, depending on the size of your brew or system.
Care Tips:
After every use, always rinse your airstones thoroughly. Compost tea can leave behind organic buildup that clogs the pores and harbors unwanted microbes. You don’t want to carry that over into your next fresh brew!
Let the stones dry completely—ideally in the sun—and consider a soak in diluted hydrogen peroxide (H₂O₂) to sanitize and remove residue. Clean airstones = healthier brews. 🌱
