works great I purchased 2 100' weighted hoses and then attached one of the alumina airstones on the end of each hose. So far they seem to really work well. The staff kindly recommended which type of connector I would need to fit the diffuser and my 1/2" ID hose.
Pros:easy to attach, good air movement
Cons:connector required to fit my 1/2" weighted hose
