Thank you Mike. I wonder if you could provide an update once you hook it up. Did it come ready to use with capacitor and all wiring? How does it look? Did you get the one with the cooling fan attached to the bottom and the mounting bracket? I might just press the button on one of them. From the reading I've done here on that specific pump it seems like it will work good, I'm just concerned that it would be overkill for a single membrane diffuser. Maybe there's no such thing as overkill. Oh, last question, I swear, is it really loud? Thanks again!
