Aquario Neo Air diffuser Special Type Large 

Neo diffuser for Air produces uncomparably tiny air bubbles to other air stones. Micro bubble doesn’t make such a noise as it from other air stones and doesn’t splash around. Its large surface area increases dissolved oxygen in the aquarium. Neo diffuser is made of transparent acryl, which is not easily broken differently from glass diffusers when separating from the aquarium and cleaning. Simple design is well matched with not only a big aquarium but also a mini.

Available sizes:
Medium - 17 mm diameter - for 100-200 liters
Large - 24 mm diameter - from 200 liters
