Aqua Medic Wooden Airstone Mini 2pcs produced from lime wood with very fine pores
Aqua Medic Wooden air stones are produced from lime wood with very fine pores. They have low pressure resistance and create very fine, even bubbles. To keep the skimmer running at its optimum performance level, the bubbles have to be monitored regularly, and is recommended that the air stone is changed every 6-8 weeks.
The air stones are available in 3 sizes:
Mini – 50 mm (2 pieces), for the Miniflotor
Midi – 65 mm (2 pieces), for the Midiflotor
Maxi – 88 mm (one piece), for big skimmers
