This air diffuser membrane is an OEM product from Aqua Exclusive™ which is designed for use in the air diffuser of the Green Line Bio Filter. The air diffusers are a crucial part in the bio filter, because they provide massive water displacement resulting in optimal degassing and oxygen enrichment of the water. Over time the material may wear out and begin to crack eventually requiring a replacement. This item is sold individually and is made of durable rubber. Note, do not use a cordless screwdriver, but loosen and tighten screws by hand with an hex key.
