EasyPro Details

Product Detail These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and destratifying applications
Product Detail Unlike air stones these diffusers are easy to clean
Product Detail In testing they produce a slightly larger air bubble than air stones which translates into less oxygen transfer into the water, so for fish holding tanks, raceways, fish production ponds, etc. we recommend air stones
Compatibility Barbed inlets have multiple size barbs, simply cut to fit the size tubing you are using
Product Detail An excellent choice for pond and water garden aeration since they actually produce more circulation and water movement

Before You Buy

Great Buy, Great Customer Service

I’m really impressed by the customer service from this company. Tony the owner personally walked me through the entire process, answering all my questions and making sure I felt completely confident in my order. I couldn’t be happier with the EasyPro SMF1800 filtration system it’s a powerful unit, and it’s working perfectly for my needs. I’m so glad I was recommended this product! I’ll definitely be buying all my pond supplies from here moving forward, and I’ve already told Tony that. I highly recommend supporting this business!
