Bobby, my pump is completely silent and it is the same rebranded Medo pump, bought new from Jehmco. I'm extremely pleased with the silence of the pump. All I hear is the noise of the bubbles.
I was referrring to the noise generated by the regenerative blowers.
I wanted to add that I did tee off the main header and ran it into the next room over and it is supplying 6 additional 24"L x 18"W x 15"H tanks so there is currently 20 tanks running off the LPH60 pump with more air to spare.
Ok. I guess I misread your post. LOL
I'm running an LPH80 and have at least 46 outlets running. I still have room to go.
